Method and apparatus for determining heating value of fuel gases

Method and apparatus for determining a heating value of a sample hydrocarbon-containing mixture having hydrocarbons and non-hydrocarbons as mixture components. The sample is reacted with an excess amount of oxidant gas in a reaction chamber to form a product gas containing residual oxygen. The molecular weight of the sample is measured and the residual oxygen concentration of the product gas is measured. The heating value is calculated from the measurements of the molecular weight and the residual oxygen concentration. Pure component hydrocarbon gases may be used to calibrate the system. 用于测定具有烃和非烃作为混合物组分的样品含烃混合物的热值的方法和装置。使样品与过量氧化剂气体在反应室中反应，以形成包含残余氧的产物气体。测定样品的分子量，并测定产物气体的残余氧浓度。从分子量和残余氧浓度测定结果计算热值。可用纯组分烃气体校准系统。
