It moves it to do work and make electrical power generators, the steam come out from turbine low pressure cylinder condenses into water through condenser, then through oxygen-eliminating device
Deoxygenation finally by feed pump is transported to boiler,
The utility model optimal technical scheme is to also set up external steam-water separator, the steaming come out from steam turbine high-pressure cylinder
Vapour first through the external steam-water separator, enter back into the resuperheater later.
The utility model optimal technical scheme is that the resuperheater is arranged in the inside steam drum.
The utility model has the beneficial effects that the utility model proposes a kind of waste incineration and generating electricity high parameter drum among again
Hot systems also set up resuperheater in inside steam drum, and the steam that boiler generates initially enters steam turbine high-pressure cylinder, it is driven to do
Function simultaneously makes electrical power generators, and the steam come out from steam turbine high-pressure cylinder enters the resuperheater and heated again, later
Turbine low pressure cylinder is entered back into, drives it to do work and makes electrical power generators.Using the saturated vapor in drum in resuperheater
In, the steam after steam turbine high-pressure cylinder acting is heated again, then returns to continue to expand in turbine low pressure cylinder and do
Function, to improve thermal efficiency of cycle and generating efficiency.Since drum has certain buffer capacity, drum to boiler load variation
Interior vapor (steam) temperature variation is smaller, to keep the variation of resuperheater steam temperature steady, temperature adjustment amplitude is smaller, gives resuperheater temperature adjustment
