Mid-low temperature waste heat recovery power generation system for cement kiln ZL200720038566.9
Abstract: The utility patent involves a kind of power generation system, that is, mid-low temperature waste heat recovery power generation system for cement kiln which includes clinker cooler, SP, AQC boiler, SP boiler, AQC drum, SP drum, turbine, feed water pump, dust-collector, fans and chimney. The inlet of the waste gas from AQC boiler has a public high-temperature superheater while the superheater of the SP boiler get together to the same point with the superheater of the AQC boiler. The outlet of the point connects with the inlet of the public high-temperature superheater through pipelines, then the outlet of the public high-temperature superheater links with the turbine, also through pipelines. Steam from superheater of SP boiler mix with that from AQC boiler, and then to be heated again, the temperature nearly the same before they get mixed which can reduce or avoid the phenomenon of entropy, the temperature and flow rate of the superheated steam from the inlet of the turbine also improved, thereby can increase the generation capacity.
