水泥新型干法窑与机立窑清洁生产水平之比较

Clean Production of Cement Dry Kiln and Vertical Kiln

分工艺设备与投资、资源综合利用、产品质量、能源消耗、产品成本与劳动生产率、污染物产生与排放及环境管理水平等方面对新型干法窑与典型机立窑进行了清洁生产水平的比较,结果显示新型干法窑比机立窑有着无可比拟的优势,因此对水泥机立窑应采取淘汰、限制、改造及提高政策。

The clean production levels of cement dry kiln and vertical kiln were compared in terms of process equipment and investment, resource utilization, product quality, energy consumption, product cost and labor productivity, pollutant generation and discharge as well as environment management. Results indicated that cement dry kiln is advantageous over vertical kiln and vertical kiln should be dismantled or renovated.
