by Honktown Mon Jan 06, 2020 6:52 pm, Post The optimal ratio of accumulators per solar panel relies on many values in the game. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. by Honktown Mon Dec 02, 2019 1:56 pm, Post A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . All rights reserved. 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. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). by disentius Tue Jan 07, 2020 9:36 pm, Post Thanks. There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. This page was last edited on 13 September 2019, at 23:48. These fuel cells are then burned in a nuclear reactor to create heat. Do your pipes have water? Is there any info about how much water per second Heat Exchangers use? Someone already mentioned the normal "build on a lake" strategy. by steinio Fri Jan 03, 2020 4:52 pm, Post 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. Nuclear power plants mostly need a lot of water. Not sure where you got those numbers from, but in 0.15, small pumps and offshore pumps pump at exactly the same rate: 1200 fluid/s. A heat exchanger consumes 10 MW.

An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. The number of boilers can be derived from the number of steam engines: 40 2 = 20. 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). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. So you have 10 + 12 = 22 pipes. There's no clear ratio as you need to account for heat bonus from other reactors but it's quite easy to calculate yourself, if you fuel the reactors it will show you produced heat in MW (with bonus) you just sum up all reactors and divide by heat exchanger power (all power/power per 1 hear exchanger) to get the number, then you do the same for turbines (all power/power per 1 turbine). Don't ask me how that works.). by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. 6, crafting time is 15s, producing 0. The flow between pipes and heat exchangers is also different to pump to heat exchangers. The water calculation has me stumped. Until then it is advisable to not use more than one pump per water network. using 3 pumps and a tank, you can feed 28 heat exchangers. So a 2x2 block produces 480MW (4*3*40). 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. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. Geplaatst op 3 juli 2022 door . by Bauer Wed Jan 08, 2020 3:04 pm, Post The offshore pump produces water from a lake or ocean. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. It took me 4 days to figure out the ratios related to nuclear power, so I figured I'd share. by disentius Fri Nov 29, 2019 9:15 pm, Post 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. by mrvn Wed Jan 08, 2020 3:42 pm, Post 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 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. Don't ask me how that works.) 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. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. They represent the number of modules. The Factorio devs plan some refactoring for the upcoming version 0.17. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. 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. Tileable Nuclear Reactor Design. Now you have 0 waste of fuel. All rights reserved. It produces 1200 units of water per second. by Amarula Fri Jan 03, 2020 4:45 pm, Post Heat exchangers will not produce steam until they reach 500C. 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. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. 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. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. #footer_privacy_policy | #footer . If you want a ratio that's a little easier to remember, those are probably your best bet. Are there enough steam generators (boilers, heat exchangers)? 9.89 gigawatts is a lot. Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . Reddit and its partners use cookies and similar technologies to provide you with a better experience. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. 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.

Press J to jump to the feed. 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. There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. 20. Look at the windows in the pipes, hover over the pipes! Additional comment actions. The steam produced is exactly 500C hot, even if the exchanger is hotter. All trademarks are property of their respective owners in the US and other countries. At full 10 MW load this is 103.096 water per second. Give exchanger max heat you can then let the exchanger turn 25k water into steam. See also the applied power math tutorial to answer the question how much coal do I need? One boiler consumes 1. Each turbine consume 60 water/s so 1200/60=20 turbines. My own personal Factorio super-power - running out of power. 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. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. 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). Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. 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. by Honktown Fri Jan 03, 2020 8:34 pm, Post Using steam engines for power does not produce pollution, however using boilers to heat up the water does. In theory, there is no difference between theory and practice. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. This page was last edited on 27 October 2020, at 13:19. by Amarula Mon Dec 02, 2019 3:51 pm, Post 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. Added high graphics quality option for the steam engine. That's actually just odd. It does not require electricity or fuel to operate. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. Pump Ratio ^ 1. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. You can check the usage on the turbines as well as the production stat on the offshore pump. 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. 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. 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 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. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Heat exchangers will not produce steam until they reach 500C. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. Don't know how to use a machine? Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? Reddit and its partners use cookies and similar technologies to provide you with a better experience. by leitk Mon Dec 02, 2019 4:29 am, Post and our by Amarula Fri Nov 29, 2019 3:09 pm, Post 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. 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 lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. In practice, there is. 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. Yes, there is also a maximum throughput for water that depends on the distance the . So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? And probably how many Offshore Pumps you need for them? (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. SmartAlec105 having more than 2 steam engines per boiler could do that. What does clicking on an item's icon in the "Factory" tab do? If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. This ratio is. 15 - Factorio Factorio Forums View topic - 0. Use the lake west of your copper mine. Each turbine consume 60 water/s so 1200/60=20 turbines. by azesmbog Fri Nov 29, 2019 4:19 pm, Post The heat exchanger exchanges heat between a heat connection and water to produce steam. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. A heat exchanger consumes 10 MW. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. 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. Cookie Notice Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. This equation could also be used to remember the vanilla optimal ratio given its simplicity. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Heat exchangers produce ~103 steam with a temperature of 500C every second. 1 offshore pump: 20 Steam Turbines. 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. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). Refer to Francis John play through video on YouTube on nuclear power. by mrvn Fri Nov 29, 2019 4:41 pm, Post Each boiler is capable of producing enough 165C steam for two steam generators. 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). However you did warn me: Save often and reload if necessary during landfilling. by astroshak Sat Jan 04, 2020 1:58 am, Post Press question mark to learn the rest of the keyboard shortcuts. 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. This page was last edited on 16 February 2022, at 11:27. This produces the 1:20:40 ratio. All trademarks are property of their respective owners in the US and other countries. One offshore pump can supply 20 boilers and 40 steam engines. One pump can supply up to 20 boilers. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. 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. 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. The technical implementation details of Factorio's pipe system still have some room for improvement. HolyGarbage . Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? So I've run into an issue with water for my Turbines. This means the energy that was put into the steam to heat it to a higher temperature is wasted. The steam produced is exactly 500C hot, even if the exchanger is hotter. It takes 200J to heat 1 unit of water by 1C. fox hill country club membership cost. can you post a screenshot/blueprint? fox hill country club membership cost. Heat exchangers produce ~103 steam with a temperature of 500C every second. You may also use this to rectify brownouts/blackouts. 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 There are also times between day and night called dusk and dawn which complicate the calculations. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. How do you set up a reactor to get enough water to keep producing steam? So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. (100% neighbor bonus per adjacent reactor). Steam engines are the most basic electricity generator, available to the player at the start of the game. Steam engines have two ports, allowing excess steam to flow through. 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. 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. 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. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? 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. Valve Corporation.
