Calorimetry as an effective method to measure heat value of combustible gases
This article examines the methods applied for the calorimetric measurements of the volumetric heat value of combustive gases: authors give the accuracy requirements, classi cation and work principles for the heat value measuring instruments. They stress the topicality of the questions related to the named measurements, and analyze the metrological and technical characteristics of the measuring instruments which realize the calorimetric methods. Authors demonstrate expedience and potential of the calorimetry applications in heat power engineering and the metal production either for commercial accounting of mutual payments for natural gas, or for settlement of the technological tasks, and together with a popular computational method while solving di erent measuring problems.
