Waste Heat Recovery System

The Waste Heat Recovery system can largely reduce the power consumption of cement production, hence increasing the price competiveness of the cement products. Cement production line is the process which consumes big quantity of heat (100 115kg standard coal/t clinker) and power ( about 90115kwh/t clinker). During the burning process of clinker, the waste heat below 400 emitted from pre-heater and grate cooler accounts for more than 30% of the total heat consumption If the exhaust gas can be recycled and transferred into power for cement production, it is helpful to reduce the total power consumption for clinker production by 60% and above 30% for cement production. It greatly decreases the quantity of power which cement factories need to buy from local power plant or is produced by its own power plant, so as to reduce the production consumption. Besides, it cuts down greenhouse effect which may be caused by direct emission of exhaust gas into the air. Meanwhile, it also cuts down fuel consumption of power plants which supply electricity for cement factories. And less emission of CO2 and other burning wastes is useful for environment protection. SEPEC can supply all scale of low temperature waste heat power generation system, with possess technology of single pressure, double pressure, flash evaporation and so on, to maximize profit for clients by utilizing the proper proposals according to the specific conditions of plants. Following the principles of generation from heat, save power and environment protection, considering the process of clinker produce, general layout, electricity distribution, water supply system equipments, the system can take a good use of waste heat from the outlet and inlet of the kiln.
