This paper introduces present situation at home and abroad, and the processes of the lime kiln combustion control, propose a set of Kingview 6.52 and OMRON PLC lime kiln combustion control system design scheme based on, according to the requirements of the lime calcining process and the control, the calcining zone temperature as control object, through of the gas and air transportation volume control combustion.The software program of the control system is designed and debugged, which realizes the communication between the upper and lower computer and the monitoring of the system.The system has stable performance, high reliability, good control effect, and it has certain application value. Keywords: lime kiln combustion control; Kingview; PLC。 目录 第一章 绪论 1 一、课题背景 1 二、石灰窑简介 1 三、石灰的应用 2 第二章 石灰的生产控制 3 一、石灰的煅烧机制和影响因素
