【摘要】：水泥生产过程中主要热量损耗在于窑尾预热器出口废气带走热、窑系统表面向环境通过辐射及对流方式传导热量、窑头熟料冷却机余风带走热和出冷却机熟料带走热损失等。研究水泥窑尾预热器表面耗散热和回转窑筒体热回收技术,是提高水泥厂能量利用率的重要措施。为了在预分解窑更高效的使用能源审计分析。本文从能量平衡的角度分析了预分解窑系统的能源利用及损失情况,研究了耐火材料降低预热器筒热损失及利用二级窑壳回收回转窑表面余热的情况,提高水泥窑系统的能源利用率。
[Abstract]:The main heat loss in cement production lies in the exhaust gas heat taken away from the outlet of the kiln end preheater, the heat transfer from the kiln system surface to the environment through radiation and convection, the residual heat from the kiln head clinker cooler and the heat loss from the outlet cooler clinker. It is an important measure to improve the energy utilization ratio of cement plant to study the heat dissipation on the surface of cement kiln end preheater and the heat recovery technology of rotary kiln tube. Audit analysis for more efficient use of energy in precalciner kilns. In this paper, the energy utilization and loss of precalciner kiln system are analyzed from the point of view of energy balance, and the situation of reducing heat loss of preheater drum and recovering residual heat of rotary kiln surface by using secondary kiln shell are studied. Improve the energy efficiency of cement kiln system.
