摘　　要：为有效预测气化炉炉内耐火砖减薄的程度,气化炉安装有表面测温系统,而炉表面温度间接地反应了耐火砖使用情况。表面测温系统是保证气化炉安全运行的重要设施,主要由测温元件、安装附件和多路温度采集系统组成,通过Modbus方式与DCS系统实现冗余通信,相比传统4mA^20mA方式可节约大量资金和减少安装、维护工作量。To effectively predict the extent of the gasifier furnace refractory bricks thinning,gasifier installation has a surface temperature measuring system,the surface of the furnace temperature indirectly reflect the usage of refractory brick and surface temperature measurement system is one of the important facilities,to ensure the safe operation of the gasifier is mainly composed of temperature measuring element,installation of attachment and multi-channel temperature acquisition system,by way of the Modbus redundant communication with DCS system,compared with the traditional way of 4-20 ma can save a lot of money and reducing installation and maintenance workload.
