摘　　要：介绍一种热值仪的工作原理、性能和安装要求。搭建热值测定实验系统,与在线色谱仪比对,分别对常规管道天然气和煤制天然气进行热值测定。对于常规管道天然气,采取修正系数修正后,与在线色谱仪测量结果平均相对误差为0. 136%。对于煤制天然气,热值仪的热值计算方法中未考虑氢气组分,热值关联模型和参数应该体现氢气组分的影响。The working principle,performance and installation requirements of a calorimeter are introduced. An experimental system for calorific value measurement is set up,and compared with on-line chromatograph, the calorific value of conventional pipeline natural gas and synthetic natural gas from coal are measured respectively. For the conventional pipeline natural gas,the average relative error with on-line chromatographic measurement is 0. 136% after being corrected by the correction coefficient. For the synthetic natural gas from coal,the calorific value calculation method of calorimeter does not consider hydrogen components,and the calorific value correlation model and parameters should consider the influence of hydrogen components.
