Paper Title:
Study on Process Control Method of Kiln Outlet in Cement Production
  Abstract

This paper describes a configuration method of kiln outlet production line in which a new integrated control system PCS7 of Siemens is used. From the raw feeding to the clinker storage, and from measurement unit at the bottom to management at the upper system, the configuration realizes a transversal and vertical integration and automatic control of the productive process. The operational principle of the kiln, burning process of raw power, pulverized coal and hot airflow in the kiln and cooling procedures and transportation of clinker in grate cooler are all analysed at length. The control requirements, influencing factors and controlling methods of the secondary air flow, which is the most important factor in all process parameters, are analysed in detail, and the control loops of opening degree of valves and the speed of waste gas fan are designed to improve and stabilize the temperature of secondary air flow.
