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). A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . And probably how many Offshore Pumps you need for them? 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. Factorio version: 0.17 - 1.1 Downloaded by: 6.01K users Summary Adds scaled up versions in different sizes for various pipes and pumps. It must be placed on a shoreline of a body of water on the map, and connected to a pipe or other object that accepts liquids. A heat exchanger consumes 10 MW. All rights reserved. This page was last edited on 16 February 2022, at 11:27. One offshore pump can supply 20 boilers and 40 steam engines. 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. 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 ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. This link for calculations. 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. #footer_privacy_policy | #footer . Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? So a 2x2 block produces 480MW (4*3*40). I think it is easiest to just have an abundance of storage tanks for the steam. Hence, each water pump can support a maximum of 40 steam generators. 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. 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. 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. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. by Amarula Mon Dec 02, 2019 3:51 pm, Post (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. At full 10 MW load this is 103.096 water per second. 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 layout produces 40 MW output ( 1 SRE ). 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. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. You can check the usage on the turbines as well as the production stat on the offshore pump. 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). A steam turbine consumes 60 units of steam per second, which is 5.82 MW. But the water only gets heated up from 15C to 500C, so by 485C. Reddit and its partners use cookies and similar technologies to provide you with a better experience. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. 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. Heat exchangers have different dynamics to actual pipes. Heat exchangers produce ~103 steam with a temperature of 500C every second. They represent the number of modules. There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. 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. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. It takes 200J to heat 1 unit of water by 1C. Each offshore pump outputs 1200 units of water per second. 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. The steam produced is exactly 500C hot, even if the exchanger is hotter. 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, You will need 1x2 chunks space near water, so anywhere, maybe next to Oil Field's Uranium patch. So I've run into an issue with water for my Turbines. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? However I want to do a different configuration and want to plan out how many of each type of component I need. Using steam engines for power does not produce pollution, however using boilers to heat up the water does. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. This means the energy that was put into the steam to heat it to a higher temperature is wasted. Tileable Nuclear Reactor Design. Steam engines have two ports, allowing excess steam to flow through. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Additional comment actions. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. It produces 1200 units of water per second. 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. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988.

Or so. 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. Get some landfill to straighten the edge youre gonna use. 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). using 3 pumps and a tank, you can feed 28 heat exchangers. by astroshak Wed Jan 08, 2020 11:15 am, Post One offshore pump can supply 20 boilers and 40 steam engines. Connect water tank to exchanger for exactly 25k units water. by disentius Tue Jan 07, 2020 9:36 pm, Post Heat exchangers produce ~103 steam with a temperature of 500C every second. Don't ask me how that works.) What does clicking on an item's icon in the "Factory" tab do? Any experiences/suggestions/comments are welcome. 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. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Nuclear power plants mostly need a lot of water. by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. Valve Corporation. The number of boilers can be derived from the number of steam engines: 40 2 = 20. The heat exchanger exchanges heat between a heat connection and water to produce steam . Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. Create an account to follow your favorite communities and start taking part in conversations. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. 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. Looking for efficient setups? by gGeorg Sat Dec 07, 2019 1:00 am, Post 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. Valve Corporation. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. 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. In theory, there is no difference between theory and practice. Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . by Honktown Mon Dec 02, 2019 1:56 pm, Post All rights reserved. can you post a screenshot/blueprint? Try this checklist before you completely revamp your power source. 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.
