The maximum pressure that two more than heat boiler place create advocate filling steam is entered to coagulate through be in charge of after vapour classics mixes steam type turbine, conduit of filling steam of low-pressure vapour classics fills turbine; Steam of turbine rear lack enters condenser, condensate enters vacuum deoxidize through condensate pump and conduit implement, in deoxidize implement inside the water after classics deoxidize enters boiler through boiler feed pump; The pipeline after the waste gas classics of generation of kiln end intake air heater transforms cement product line introduces kiln end more than heat boiler, the pipeline of waste gas classics after heat exchange enters raw material to grind, again via collecting dust implement from chimney eduction; The convulsions mouth that generation of grog of cooling water mud heats up cold machine of 箆 of airy kiln head by caudal reach, the bleed mouth with the cold mid machine of comb with a double-edged fine-toothed comb of waste gas classics that 350 ℃ control, enter kiln head by bleed pipeline more than heat boiler, the flue gas of the about 95 ℃ after heat exchange enters dust catcher, emit into atmosphere through chimney.
The overheat steam that more than heat boiler produces more than heat boiler and kiln head carries kiln remaining part into steam fast close a powerful person to enter turbine; Kiln head double the filling steam mouth that the low-pressure vapour that presses generation of more than heat boiler passes turbine sends turbine; Vapour undertakes inside turbine energy is changed, turbine procrastinates move a dynamo to undertake generating electricity; The lack steam after acting enters condenser, condensate seals heater to enter vacuum deoxidize through the axis implement, send kiln the head through water supply pump next double press more than heat boiler; The much that more than heat boiler produces kiln head advocate the part that more than heat boiler produces vapour and kiln remaining part advocate vapour and low-pressure vapour never are the same as place to enter turbine respectively; Kiln head water of blowdown of more than heat boiler carries remaining part of more than heat boiler, kiln blowdown conduit enters container of the enlarge that decide a platoon and container of the enlarge that join a platoon respectively, the sewage inside container of the enlarge that decide a platoon and container of the enlarge that join a platoon is entered drop in temperature pool.
Condenser water turns into after condenser of classics of steam of turbine rear lack is cooling, the pump of water supply of water supply classics that warp beam seals heater to heat to make an appointment with 56 ℃ enters kiln head boiler, water supply passes superheater of evaporator of communal heater, low-pressure evaporator, low-pressure superheater, high pressure, high pressure early or late, have converse convection heat exchange with flue gas; After water supply is heated to become saturated hot water in communal heater, cent becomes road of 3 be in charge of to enter drum of low pressure of kiln head boiler respectively, drum of high pressure of kiln head boiler and heater of kiln end boiler; After the saturated water that enters drum of boiler of kiln head low pressure passes low-pressure evaporator, low-pressure superheater, be heated low-pressure overheat vapour; The saturated water course that enters drum of boiler of kiln head high pressure turns high-pressured overheat into vapour after superheater of high-pressured evaporator, high pressure; After the heater of the interior of boiler of end of kiln of saturated water course that enters heater of kiln end boiler, evaporator and superheater and flue gas have converse convection heat exchange, be heated high-pressured overheat vapour; Turbine is entered after the pipeline of classics of high-pressured overheat vapour of two boiler mixes advocate steam door; The low-pressure overheat steam that kiln head boiler produces enters mouth of turbine filling steam.
