Reddit and its partners use cookies and similar technologies to provide you with a better experience. In general, nuclear power is produced by the following production chain: Uranium ore is mined and processed to uranium-235 and uranium-238, then uranium fuel cells are created from the two. by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. by astroshak Wed Jan 08, 2020 11:15 am, Post Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . r/factorio . For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. Using steam engines for power does not produce pollution, however using boilers to heat up the water does. makes troubleshooting easier. P UMPING U NITS M EETING P HYSICS S TANDARDS This mod started off as a project to sustain my most eco-unfriendly excessive water needs by implementing some Higher Tier Offshore Pumps. This produces the 1:20:40 ratio. #footer_privacy_policy | #footer . by Bauer Wed Jan 08, 2020 3:04 pm, Post A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. I concur the ratio is 1:1 cerified through testing. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Mark IIIs are unable to complete a full cycle without going into meltdown and thus need to be shutdown mid-cycle in order to deal with the high amount of excess heat. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). Don't ask me how that works.). The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. by leitk Mon Dec 02, 2019 4:29 am, Post Does the game consider 1 water = 1 steam (just a different temperature?) Espaol - Latinoamrica (Spanish - Latin America), https://wiki.factorio.com/Tutorial:Nuclear_power#Neighbor_bonus. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. Hovering the mouse over a steam engine will display their current power production (Performance) and their possible power production (Available Performance), in a display on the right. These include the power generation of a solar panel, the energy storage of an accumulator, the length of a day, and the length of a night. Do your pipes have water? If the only effect the mod has on the game is it changes the total length of one day, without changing the ratio of dusk: day: dawn: night, then the equation can be simplified as. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. One offshore pump can supply 20 boilers and 40 steam engines. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. The heat exchanger exchanges heat between a heat connection and water to produce steam . Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Don't know how to use a machine? This equation could also be used to remember the vanilla optimal ratio given its simplicity. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. by Amarula Fri Nov 29, 2019 3:09 pm, Post Remember that water in pipes still obeys Factorio physics; if you pipe your water a long distance, you may not get the full 1200/s. 6, crafting time is 15s, producing 0. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. Heat exchangers produce 103 steam/second.This can be calculated by relying on steam turbine data: A steam turbine consumes 60 steam/second and produces 5.82MW (assuming 500C steam). A heat exchanger consumes 10 MW. To heat up 1 unit of water 1 degree, 200 joules are needed, so the heat exchanger is heating up water by 50,000C in total. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. Also iirc tanks limit liquid throuput when it flows through them, so try connecting them on the side and not in-line if you have to at all. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. The heat exchanger exchanges heat between a heat connection and water to produce steam. On a lake, very carefully - they consume a monstrous amount of water, and having the multiple required offshore pumps integrated directly into the design is often worth the hassle of wrangling landfill. The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). Pump Ratio ^ 1. Heat exchangers produce ~103 steam with a temperature of 500C every second. If not, ensure all. It takes 200J to heat 1 unit of water by 1C. In theory, there is no difference between theory and practice. Electricity has to be produced before it can be transferred to consumers over the electric system. Try this checklist before you completely revamp your power source. There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. Nuclear reactors have a maximum temperature of 1000 C. Unlike boilers, nuclear reactors will not slow or stop their fuel consumption if their output isn't being used; they'll constantly use up fuel cells at the normal rate of 1 fuel cell / 200 seconds. Press question mark to learn the rest of the keyboard shortcuts. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. So a 2x2 block produces 480MW (4*3*40). Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. by azesmbog Fri Nov 29, 2019 4:19 pm, Post 1 offshore pump: 20 Steam Turbines. you can put 4 heat exchangers at the end of ~135 heat pipes, but you can put 16 heat exchangers only at the end of ~50 heat pipes. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. Fresh water is at 15C while the steam produced by heat exchangers and consumed by steam turbines is at 500C, a difference of 485C, so you need 1 unit of water for each 97kJ, which is roughly 10.3 units per MJ. 12. In practice, there is. Press J to jump to the feed. All rights reserved. by gGeorg Sat Dec 07, 2019 1:00 am, Post (100% neighbor bonus per adjacent reactor). Exchanger outputs to 2 tanks. A perfect square of reactors has the highest theoretical efficiency, but at 3x3 and above you'll have reactors surrounded on all 4 sides and have no way to load the uranium fuel cells. The steam produced is exactly 500C hot, even if the exchanger is hotter. The offshore pump produces water from a lake or ocean. Use the lake west of your copper mine. There are also times between day and night called dusk and dawn which complicate the calculations. They only work when they're above 500 C, and have a maximum temperature of 1000 C. Temperatures above 500 don't increase efficiency; the exchanger will just store the heat, which it can then use later. Yogi Berra. . Hence, each water pump can support a maximum of 40 steam generators. Additional comment actions. It does not require electricity or fuel to operate. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. Community-run subreddit for the game Factorio made by Wube Software. The technical implementation details of Factorio's pipe system still have some room for improvement. If you want a ratio that's a little easier to remember, those are probably your best bet. Press question mark to learn the rest of the keyboard shortcuts. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines Create an account to follow your favorite communities and start taking part in conversations. The throughput of a fluid pipe depends on the length of said pipe, but you can put in pumps to pressurize the pipe and increase the throughput. You can sideload water for a 1.1 GW plant. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines, 2 reactor = 160MW = 16 exchangers = 28 turbines, 4 reactor = 480MW = 48 exchangers = 83 turbines. This link for calculations. factorio offshore pump heat exchanger ratio A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. If you inexplicably want to go back to a 4 year old build of Factorio then you will need to build 14 boilers in a row (they each used to heat the water up by a little bit), followed by 10 steam engines. The true value comes from the following facts: It takes 1 kilojoule of thermal energy to raise 5 units of water/steam 1 C, You've heated water from 15 C to 500 C; 500 - 15 = 485, Consuming steam in turbines gives you the same amount of energy back as electricity, Steam is consumed by steam turbines at a rate of 60 units/second. Connect water tank to exchanger for exactly 25k units water. Someone already mentioned the normal "build on a lake" strategy. If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. All trademarks are property of their respective owners in the US and other countries. Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. HolyGarbage . The flow between pipes and heat exchangers is also different to pump to heat exchangers. Is steam able to reach all steam engines? My own personal Factorio super-power - running out of power. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. by disentius Tue Jan 07, 2020 9:36 pm, Post Calculator for the Nuclear Reactor. Each boiler is capable of producing enough 165C steam for two steam generators. One steam engine consumes 30 steam per second, and one offshore pump produces 1200 water per second, so each offshore pump produces enough water to supply 40 steam engines: 1200 unit/s 30 units/s = 40. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. Ratio of reactors to whatever is 2x2 480MW reactor to 10MW heat exchanger, ratio of reactors to miners is 1:4 iirc, so double that miners. So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. Tutorial:Main bus. The water calculation has me stumped. Steam engines are the most basic electricity generator, available to the player at the start of the game. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Is there any info about how much water per second Heat Exchangers use? So I've run into an issue with water for my Turbines. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Reddit and its partners use cookies and similar technologies to provide you with a better experience. All rights reserved. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. You may also use this to rectify brownouts/blackouts. Community-run subreddit for the game Factorio made by Wube Software. Perfectly optimal solar network (Factorio forums), 1 solar panel produces 42KW after factoring in the night (Factorio forums), https://wiki.factorio.com/index.php?title=Power_production&oldid=182968. Valve Corporation. If I know how much energy i'm outputting from my reactors -> figure out how many turbines -> figure out how many heat exchangers -> How many pumps do I need? Each offshore pump outputs 1200 units of water per second. This page was last edited on 16 February 2022, at 11:27. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. by Amarula Fri Jan 03, 2020 4:45 pm, Post A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Nuclear power plants mostly need a lot of water. Sushi Belt question : r/factorio. SmartAlec105 having more than 2 steam engines per boiler could do that. Press J to jump to the feed. by disentius Fri Nov 29, 2019 9:15 pm, Post The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. Additional comment actions. Factorio version: 0.17 - 1.1 Downloaded by: 6.01K users Summary Adds scaled up versions in different sizes for various pipes and pumps. One boiler consumes 1. Espaol - Latinoamrica (Spanish - Latin America). The most heat exchangers I've been able to fit on a single length of heat pipe is 30 heat exchangers on 44 heat pipes; any more than that incurs significant heat loss. All trademarks are property of their respective owners in the US and other countries. You can check the usage on the turbines as well as the production stat on the offshore pump. fox hill country club membership cost. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. One offshore pump can supply 20 boilers and 40 steam engines. You can also have some steam tanks with additional turbines for power spikes (laser turrets etc) as reactors always work with 100% power tanks will store steam when you're not using it all), Factorio Cheat Sheet - That's all the information you need. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. That's actually just odd. So you have 10 + 12 = 22 pipes. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). A "close enough" ratio is 20:24:1 accumulators to solar panels to megawatts required (for example, a factory requiring 10 MW can be approximately entirely powered, day and night, by 200 accumulators and 240 solar panels - this approximation differs from optimal only in that it calls for 20 extra solar panels, which is negligible but remember that the difference between the "close enough" ratio and the optimal ratio increases as you add more solar panels). Each turbine consume 60 water/s so 1200/60=20 turbines. Stuck in a mission? Get some landfill to straighten the edge youre gonna use. by eradicator Fri Nov 29, 2019 4:43 pm, Post But the water only gets heated up from 15C to 500C, so by 485C. One pump can supply up to 20 boilers. It produces 1200 units of water per second. Thanks. Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? 1 25k tank water disconnected from water input. One exchanger 3 storage tanks plus inf heat.

Each turbine consume 60 water/s so 1200/60=20 turbines. Or so. Cookie Notice Heat exchangers will not produce steam until they reach 500C. Introduction Troubled by pipes having low flow rates? 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? 1 electric pump can keep up with rate of roughly 10 water pumps if i recall, so at least you don't need to have pump and waterpump flows in parallel. Tileable Nuclear Reactor Design. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. This page was last edited on 13 September 2019, at 23:48. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. Each steam turbine take a maximum input of 60 units of 500 C steam per second and outputs 5.82 megawatts of electricity; the 5.8 megawatts listed on the tooltip is rounded.

Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. by steinio Fri Jan 03, 2020 4:52 pm, Post Now you have 0 waste of fuel. However you did warn me: Save often and reload if necessary during landfilling. All rights reserved. Any experiences/suggestions/comments are welcome. This means the energy that was put into the steam to heat it to a higher temperature is wasted. Added high graphics quality option for the steam engine. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). Water: is a liquid which can be infinitely extracted from water tiles using an offshore pump; Steam: is a gas you can create by heating water in a boiler or heat exchanger; Other Factorio Guides: Boiler to Steam Ratio; Solar Panel Ratio; Console Commands & Cheats Each uranium fuel cell will power a nuclear reactor for 200 seconds. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. So far I have built/replaced 3 reactor sectors to be on the lake rather than beside the lake, and I am pretty happy with the results (600 fewer pipes, 800 fewer underground pipes). 9.89 gigawatts is a lot. The more heat exchangers you want to put on a single length of heat pipe, the shorter that heat pipe has to be to ensure minimal heat loss; e.g. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. These fuel cells are then burned in a nuclear reactor to create heat. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. However I want to do a different configuration and want to plan out how many of each type of component I need. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. They represent the number of modules. It takes 200J to heat 1 unit of water by 1C. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) 15 - Factorio Factorio Forums View topic - 0. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. This layout produces 40 MW output ( 1 SRE ). A heat exchanger consumes 10 MW. For more information, please see our Valve Corporation. Heat exchangers will not produce steam until they reach 500C. If your heat pipe is too long, your reactors will max out at 1000 C before your heat exchangers can reach a steady state of 500 C, and and you'll start to waste heat. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. Give exchanger max heat you can then let the exchanger turn 25k water into steam. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. One Offshore pump can fully supply 12 (11.64) . A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. Heat exchangers produce ~103 steam with a temperature of 500C every second. by astroshak Sat Jan 04, 2020 1:58 am, Post Create an account to follow your favorite communities and start taking part in conversations. At full 10 MW load this is 103.096 water per second. by Honktown Tue Jan 07, 2020 10:30 pm, Post Id probably put it on or next to either of the lakes in the middle north or middle south. Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. -adding a second off-shore pump to start off with twice as much water (in theory); -putting in more pumps, say one pump for every underground pipe; -putting in a complete second line from off-shore pump to heat exchangers with a pump every 5 underground pipes. Heat exchangers have different dynamics to actual pipes. 1 Answer. This page was last edited on 27 October 2020, at 13:19. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. And probably how many Offshore Pumps you need for them? Valve Corporation. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. If the player uses mods which change the power generation of solar panels, or the energy storage of accumulators, but not the length of days, a simplified version of this equation can be used. by mrvn Wed Jan 08, 2020 3:42 pm, Post 20. which, given the default time lengths of: day = 12500/60 s; dawn or dusk = 5000/60 s; night = 2500/60 s, and the default: Solar_power = 60 kW; Accumulator_energy = 5 MJ = 5000 kJ, gives the optimal ratio of 0.84 accumulators per solar panel. The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators). They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). Until then it is advisable to not use more than one pump per water network. Heat exchanger heats 15C water to 500C steam; It takes 0.2 kJ of burner energy to raise 1 water 1C; Steam is consumed by steam turbines at a rate of 60 units per second; (500C - 15C) 0.2 kJ 60 units = 5820 kW, or 5.82 MW. Refer to Francis John play through video on YouTube on nuclear power. Also, before you set it up, make sure you nuke any landfill land to get a little pollution absorption to help manage your Fun fumes cloud. This means that you need 1.428 MW of production (of solar panels) and 100MJ of storage to provide 1 MW of power over one day-night cycle. and our This allows steam engines to be chained together. The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side.
