煤气的热值是反映煤气质量的主要指标,它不仅关系到煤气供求双方的经济核算、能源的合理使用和燃烧的经济性,而且还影响用户操作的稳定与产品质量。随着工业发展与气体燃料品种的增加,煤气热值的测量与控制的必要性和经济价值日益显著。 在工业先进国家,煤气热值与热值指数(Wobbe Index)的测量与控制已在生产自动化中普遍应用。气体热值已列入国家计量,系统,有专门的计量单位设有气体热值测定的精密仪器,测定高纯度的甲烷、氢、一氧化碳等可燃气的热值。再把这些高纯度气体
The calorific value of gas is the main indicator of gas quality. It not only affects the economic accounting of both gas supply and demand, the rational use of energy and the economy of combustion, but also affects the stability of operation and the quality of products. With the industrial development and the increase of gas fuel varieties, the necessity and economic value of gas calorific value measurement and control have become increasingly prominent. In advanced industrial countries, the measurement and control of the gas heat value and the Wobbe Index have become commonplace in production automation. Gas calorific value has been included in the national measurement, system, a special unit of measurement with the determination of gas calorific value of the instrument, determination of high purity methane, hydrogen, carbon monoxide and other combustible gas calorific value. Then these high-purity gas
