Do power plants convert water into steam in 'batches' or at a continuous rate?
Poast new message in this thread
Date: May 20th, 2024 9:11 PM Author: Know-it-all private investor wagecucks When they burn coal or when the rods are inserted into the chamber at a nuclear plant to induce fission heat energy. Does the heat generated by either process heat a single 'tank' of water down to high pressure steam, before releasing that steam and filling up with a new batch of water? Or is there just a continuous stream of water flowing into the chambers receiving heat energy that just get continuously converted into steam and released?

Or do they more intensely evaporate the same quantity of water? (http://www.autoadmit.com/thread.php?thread_id=5530808&forum_id=2#47680397) |

Date: May 21st, 2024 3:33 PM Author: spruce disrespectful hissy fit incel all power generators have an point where they operate at optimal efficiency. different types of coal power generators have different wiggle-room in being able to vary the output. large plants will usually have multiple generators that they always operate optimally, and just vary the number of generators operating based on demand. because of advances in power storage there is less of a need for variable load flow though.

Water comes into the plant from the outside (usually from a river), where it's then treated, purified, super-heated, and pushed through a turbine to create electricity. On the other side of the turbine, the water is condensed and fed back into the system to be treated, purified, and super-heated once again. Most plants have multiple water treatment systems, and the amount of condensate passing through is insane: 16" carbon steel pipes pushing hundreds of gallons per minute at high pressure.

(probably; this is how I'd do it) |

Date: May 21st, 2024 6:54 PM Author: cracking box office heating condensate (water) in an enclosed space will cause the pressure to increase. they use super-heated (rather than saturated) steam because condensation can wreak havoc on turbines over time through steam erosion. Additionally, anything but ultra-pure condensate with low conductivity will cause even bigger problems, like boiler scale (which is almost impossible to remove), so you have to treat the condensate before it goes to the boiler to remove the undesirable stuff from it. You also want low conductivity condensate to mitigate the formation of large, unstable steam bubbles (steam bubbles won't burst as readily in water with high conductivity, leading to stability issues)
here's an example of a system that cleans condensate: https://i.imgur.com/w44atfI.png (and the control system for it: https://i.imgur.com/ZL1f3dh.png )
note the amount of condensate that each vessel can handle: 5,300 gallons per minute at 410 psig (~424.7 psia). |
