The hydroelectric power station is called a hydroelectric power station. It is a plant that converts the potential energy and kinetic energy of water into electrical energy. Its basic production process involves diverting water from high points in rivers or reservoirs and using it. water pressure or flow to rotate the turbine, convert the water energy into mechanical energy, then the water turbine drives the generator to rotate, converting the mechanical energy into electrical energy;
Where does the cold water in the plant come from and how can it be replenished? Does chemically treated water belong in an open cold water system or a closed cold water system?
Condensate - condensate pump - shaft plus - low plus - deaerator - feed water pump - high plus - economizer - steam drum - downspout - water cooling Wall—steam drum (steam separation -water)—superheater (ceiling, grille, low temperature, last stage superheater...) - high pressure cylinder steam turbine - high pressure cylinder exhaust - heater (grid, wall...) (Don't wait any longer) - Steam turbine fluid pressurized cylinder - Steam turbine low pressure cylinder - Condenser - Condensed water
This is the main process of the boiler steam-water system
Closed cold water source As for the closed cold water tank, there are two ways to replenish the water in the closed cold water tank, one is condensed water from the unit (for normal operation) and the other is l chemically demineralized water (to be used before starting the unit).
Chemically treated water is demineralized water. Demineralized water belongs to the public system and is neither open cold water nor closed cold water.
