(119), vacuum filter (119) provides vacuum by filter vacuum pump (123), and the fine ash of vacuum filter (119) delivers to boundary
Outside area, the filtrate of vacuum filter (119) is collected into filtrate receiver (121), after subsider (104) sent back to by filtrate pump (122)；Go out
Gas at the top of vacuum flasher (103) cools down in very sudden strain of a muscle condenser (111), and the liquid phase after cooling enters ash water tank (105),
Gas phase enters flash vacuum pump (112), is separated again by flash vacuum pump knockout drum (113) afterwards, and gas phase emptying, liquid phase flow to ash
Tank (105)；The liquid on subsider (104) top enters ash water tank (105), by low pressure ash water pump (106) deliver to each workshop section and
Oxygen-eliminating device (107), in oxygen-eliminating device (107), low pressure buck, raw water, convert condensate liquid, low-pressure steam, go out low pressure flash chamber
(102) gas and the liquid contact heat-exchanging of high pressure flash knockout drum (126) is gone out, the gas phase of discharge oxygen-eliminating device (107) is through dropping a hint
Emptying goes out the liquid phase of oxygen-eliminating device (107) with disperseing to torch after cooler (114) and knockout drum of dropping a hint (115) refrigerated separation
The dispersant that agent pump (125) is sent through high pressure ash water pump (108) together by delivering to grey water heater (109), and high pressure buck is with going out
The gas of hp flash drum (101) after indirect heat exchange, delivers to gasification workshop section in grey water heater (109).
The ash/usage on black water technique has the disadvantage that：
, there is limitation in flashed vapour caused by above flow mesohigh flash tank (101) and high pressure buck indirect heat exchange, heat
It is less efficient, also need the high condenser (110) that dodges further to cool down, it is necessary to consume big after height sudden strain of a muscle gas ash discharge water heater (109)
Recirculated water is measured, causes energy dissipation.
Go out in the flashed vapour of hp flash drum (101) and carry more fine ash secretly, easily cause grey water heater and block, add
Maintenance workload.
