我公司的五级双系列带窑外分解炉的预热系统中的一体化热电偶温度传感器都是用在400℃以上的测温点上,大多数都集中在窑尾预热器上。实际生产中温度变送器经常被烫焦烧坏,更重要的是传输到中控室的同级两个系列的温度也有很大的差别,这给操作员的操控带来很大的困难,于是2012年4月笔者决定利用一线定检期间解决这个问题。1原因分析预热器C4出口和下料管温度、C5出口和下料管 The integrated thermocouple temperature sensors in our five-stage dual-series preheating system with kiln outside decomposition furnace are all used at the temperature measuring point above 400 ℃, most of which are concentrated on the kiln preheater. The actual production of temperature transmitters are often scorched burn, more importantly, transmitted to the control room of the same level two series of temperature is also very different, which gives the operator control has brought great difficulties, so April 2012 I decided to use the first-line fixed-point inspection to solve this problem. 1 Cause Analysis Preheater C4 Outlet and Lower Tube Temperature, C5 Outlet and Lower Tube
