Rotary kiln waste heat power generation technology
Along with the rotary kiln cement increased demand and the shortage of power supply,80 time of our country to design and development of a number of cogeneration kiln, waste heat power generation technology has been greatly improved, operation parameters improved to about 2.5Mpa, single station installed capacity reached3000kW, power generation amount per ton clinker110-130kWh. Domestic 1500kW,3000kW steam turbine-generator set to meet the basic needs of cement plant waste heat power generation system. With the continuous advancement of technology,700t / D and 500t / D cogeneration kiln waste heat power generation system operating parameters to 3.5-3.82Mpa. Single station installed capacity reached3000kW and 6000kW. Power generation amount per ton clinker140-160kWh. The best current waste heat power generation system for generating up to180-195kWh per ton clinker. In the cement production process at the same time to produce electricity, can basically solve the production of cement power load, electricity self-sufficiency rate of above80-100%, to ensure that the output of cement, reduce expenditure of charge of electricity, improve the rotary kiln cement plant economic efficiency plays an important role in.
