水泥生产是一个高耗能行业,其排放的余热量十分惊人。仅从窑尾预热器和窑头熟料冷却机两处排出的中、低温废气中带走的余热量就占水泥生产总能耗的30%—35%。
Cement production is a high-energy-consuming industry, its emissions of excess heat is very alarming. Only from the kiln and kiln head clinker cooler clinker cooler discharged at two low-temperature exhaust gas to take the total heat of cement production accounted for 30% -35% of total energy consumption.
