对Smart 2006型热值仪的预处理单元和主机内部的相对密度测量单元、华白数测量单元的工作原理进行了介绍,该热值仪通过将二次助燃空气、环境助燃空气引入燃烧系统,保证了煤气的充分燃烧,能够提高测量的可靠性。该热值仪已在武钢热态试验室成功投运,热值测量值与同步取样分析结果相比误差小于0.2%,并且能够及时反映燃烧器试验期间燃气成分调整过程中的热值变化情况,测量灵敏度高,若将热值测量值通过热值仪预留的标准信号输出接口输出到工业炉工控机,还可望实现工业炉的燃烧自动控制。
The working principle of the Smart 2006 calorimeter pretreatment unit and the host relative density measurement unit and the Huabai measurement unit are introduced. The calorimeter introduces the secondary combustion air and the environment combustion air into the combustion system, To ensure the full combustion of gas, can improve the reliability of measurement. The calorimeter has been successfully put into operation in the WSTC laboratory and the error between the calorific value and the synchronous sampling analysis is less than 0.2%. The calorific value can reflect the change of calorific value during the gas composition adjustment during the test period, High measurement sensitivity, if the calorific value measured by calorimeter set aside the standard signal output interface output to the industrial furnace IPC, but also expected to achieve industrial furnace combustion automatic control.
