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. Electricity has to be produced before it can be transferred to consumers over the electric system. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. 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. 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? 12. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). by Amarula Fri Jan 03, 2020 4:45 pm, Post Do the numbers in the "beacons" column represent the number of modules or the number of beacons? As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. by azesmbog Fri Nov 29, 2019 4:19 pm, Post By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. All trademarks are property of their respective owners in the US and other countries. Geplaatst op 3 juli 2022 door . There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Factorio Oil Refinery The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. The flow between pipes and heat exchangers is also different to pump to heat exchangers. So you have 10 + 12 = 22 pipes. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Introduction Troubled by pipes having low flow rates? Heat exchangers will not produce steam until they reach 500C. by gGeorg Sat Dec 07, 2019 1:00 am, Post Pump Ratio ^ 1. One pump can supply up to 20 boilers. 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). 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. However you did warn me: Save often and reload if necessary during landfilling. I have been reading all about Nuclear power so I can convert my factory. 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. by mrvn Fri Nov 29, 2019 4:41 pm, Post Geplaatst op 3 juli 2022 door . The heat can be used to convert water to steam using a heat exchanger and the steam can be consumed by steam turbines to produce power.

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. 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. Steam engines are the most basic electricity generator, available to the player at the start of the game. Press J to jump to the feed. Use the lake west of your copper mine. Don't know how to use a machine? The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. by Honktown Fri Jan 03, 2020 8:34 pm, Post Create an account to follow your favorite communities and start taking part in conversations. I think it is easiest to just have an abundance of storage tanks for the steam. Thus, they can buffer 500 MJ of heat energy across their working range of 500C to 1000C, and require 485 MJ of energy to warm up from 15C to 500C when initially placed. Look at the windows in the pipes, hover over the pipes! (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Do your pipes have water? Calculator for the Nuclear Reactor. In a vanilla game that's. what, 1k science a minute? Refer to Francis John play through video on YouTube on nuclear power. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. 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. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. by Bauer Wed Jan 08, 2020 3:04 pm, Post This means the energy that was put into the steam to heat it to a higher temperature is wasted. Don't ask me how that works.). Cookie Notice The water calculation has me stumped. by steinio Fri Jan 03, 2020 4:52 pm, Post Alt-F4 #57 - Nuclear Energy and You - Alternative Friday Factorio Fan Facts Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. A heat exchanger consumes 10 MW. This produces the 1:20:40 ratio. 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. Is there any info about how much water per second Heat Exchangers use? A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. 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. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. This allows steam engines to be chained together. Id probably put it on or next to either of the lakes in the middle north or middle south. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). 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. 1 25k tank water disconnected from water input. 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. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. Factorio Calculator Yogi Berra. The steam produced is exactly 500C hot, even if the exchanger is hotter. by Amarula Fri Nov 29, 2019 3:09 pm, Post Valve Corporation. 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. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. Any experiences/suggestions/comments are welcome. Heat Exchangers not producing steam.. ? :: Factorio General Discussions As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. Valve Corporation. Nuclear Ratios : r/factorio - reddit It takes 200J to heat 1 unit of water by 1C. Tutorial:Main bus. Press question mark to learn the rest of the keyboard shortcuts. Offshore Pumps ratios and questions :: Factorio General Discussions Does the game consider 1 water = 1 steam (just a different temperature?) See also the applied power math tutorial to answer the question how much coal do I need? 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. Privacy Policy. by eradicator Fri Nov 29, 2019 4:43 pm, Post Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. Offshore pump - Factorio Wiki Post Community-run subreddit for the game Factorio made by Wube Software. There are also times between day and night called dusk and dawn which complicate the calculations. In practice, there is. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. 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. You can check the usage on the turbines as well as the production stat on the offshore pump. 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. It produces 1200 units of water per second. by Amarula Mon Dec 02, 2019 3:51 pm, Post Valve Corporation. by leitk Mon Dec 02, 2019 4:29 am, Post where game_day is the number of seconds in the game day which is 25000/60 s by default. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. This page was last edited on 13 September 2019, at 23:48. 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 3:42 pm, Post 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. 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. At full 10 MW load this is 103.096 water per second. This layout produces 40 MW output ( 1 SRE ). Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. It takes 200J to heat 1 unit of water by 1C. Or so. Espaol - Latinoamrica (Spanish - Latin America). The offshore pump produces water from a lake or ocean. They represent the number of modules. by Honktown Tue Jan 07, 2020 10:30 pm, Post 6, crafting time is 15s, producing 0. 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. 1 offshore pump: 20 Steam Turbines. Factorio Nuclear Reactor RatioThis is a site to share blueprints for Factorio Boiler To Steam Engine Ratio5/90 and add it to the pollution In theory, there is no difference between theory and practice. 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. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Additional comment actions. I concur the ratio is 1:1 cerified through testing. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. Tileable Nuclear Reactor Design. and our Try this checklist before you completely revamp your power source. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. 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. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines So I've run into an issue with water for my Turbines. Nuc power: managing a large plant :: Factorio General Discussions by astroshak Wed Jan 08, 2020 11:15 am, Post This link for calculations. All trademarks are property of their respective owners in the US and other countries. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. As far as I can tell, the absolute smallest perfect-ratio setup possible is: which would require an input of 1.46 uranium fuel cells per second and output a cool 46.56 gigawatts of electricity. 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. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) There are mods that can add landfill tiles to existing blueprints if you're up for modding and using a blueprint rather than making your own reactor, and this design is one of my favourites - not objectively "best" perhaps, but has a certain elegance that I deeply appreciate alongside a decent serving of entirely respectable practicality. Click on an empty cell to place a nuclear power plant. All trademarks are property of their respective owners in the US and other countries. Added high graphics quality option for the steam engine. Each turbine consume 60 water/s so 1200/60=20 turbines. 1 Answer. One exchanger 3 storage tanks plus inf heat. One offshore pump can supply 20 boilers and 40 steam engines. The heat exchanger exchanges heat between a heat connection and water to produce steam. Water consumption for heat exchangers math : r/factorio - reddit Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. r/factorio . Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. Factorio Reactor DesignsThis is a good measure to combat "spaghetti fox hill country club membership cost. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. Heat exchangers are pipes too. Press question mark to learn the rest of the keyboard shortcuts. Each uranium fuel cell will power a nuclear reactor for 200 seconds. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Sushi Belt question : r/factorio. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. You can sideload water for a 1.1 GW plant. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. And probably how many Offshore Pumps you need for them? When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. using 3 pumps and a tank, you can feed 28 heat exchangers. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. 15 - Factorio Factorio Forums View topic - 0. Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? 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. 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. HolyGarbage . 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. This page was last edited on 16 February 2022, at 11:27. Heat exchangers have different dynamics to actual pipes. 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.
