摘要 PAGE IV 预分解窑系统结皮的主要因素及预防措施 摘 要 随着近年来的不断演变，水泥生产方法已经进入了新型干法水泥生产线占主导地位的时代。结皮是悬浮预热器窑在生产操作过程中必须注意和防止的重要问题，必须给予足够的重视。一旦结皮就会引起整个窑系统热工制度紊乱，物料不畅通，甚至堵塞，从而使生产不能顺利的进行。本论文分析了结皮的特性、化学成分及形成结皮的原因和针对形成结皮的因素的解决措施。 严格控制原燃料的有害成分可适当的避免结皮的出现，以及严格分析煤的质和控制煤的量，加强对窑尾系统的密封，优化回转窑操作。最后对新型干法水泥的技术革新以及设备改造，还有再利用劣质燃料时对设备进行合适的选择的论述。可以使预分解窑系统的结皮得到很好的治理。 关键词：预分解窑，结皮，原燃料，硫、碱、氯循环 THE MAIN FACTORS CRUST AND PREVENTION OF KILN SYSTEM ABSTRACT With the constant evolution in recent years, cement production methods have entered the new dry cement production line dominated era. Crust is the suspension preheated kiln operation in the production process must pay attention to and prevention of important issues must be given adequate attention. Once the crust can cause the entire kiln system thermal system disorders, materials are not smooth, and even blocked, so that production can not proceed smoothly. This paper analyzes the characteristics of the skin closure, chemical composition and the reasons for the formation of crusts and crust formation factors for the solutions. Strict control of the original Fuel may be appropriate to avoid harmful ingredients Crust occur, and rigorous analysis of the coal the amount of coal quality and control, strengthen the kiln sealing systems, optimizing kiln operation. Finally, technology innovation and new dry cement equipment modification, and reuse of low-grade fuel suitable choice of equipment exposition. Making the kiln system of governance crust well.
