摘要:
建设天然气发热量直接测定参比(标准)装置是完善我国能量计量溯源链的关键步骤之一,正确理解发热量直接测定基(标)准装置建设的目标与功能、规范有关术语很重要。分析了国际标准ISO15971-2008的重点是:天然气发热量测定的术语、方法及其原理、热量计选型及其评价程序、标定、维修和质量控制,它建议以测量不确定度作为热量计分类基础。讨论了能量计量的量值传递与溯源体系,从计量学基本原理分析,发热量直接测量方法是溯源的基础。指出国内应具备完善的天然气发热量测定的溯源链,保存发热量直接测定的基(标)准装置,保证量传和溯源功能的相对权威性和独立性。给出了法制计量与参比级(0级)热量计、以及成为法定的(天然气)发热量计量监测机构应具备的功能。
Abstract:
The establishment of the direct determination reference (standard) device of natural gas calorific value is one of the critical steps to improve China’s energy metering traceability chain. It is important to correctly understand the target and the function of establishing the direct determination reference (standard) device of natural gas calorific value and to standardize the related terminologies. The focal points of the international standard ISO15971-2008 are analyzed, and they are the terminologies, the method and the principles for the determination of the natural gas calorific value, the type selection, and the evaluation procedures, the calibration, the maintenance and the quality control of calorimeter. In the standard, it is suggested to take the uncertainty degree of the determination as the basis for calorimeter classification. The quantity magnitude transmitting and traceability system of the energy measurement is discussed. From the basic principles of metrology, it is held that the direct measuring method of calorific value is the basis of traceability. It is pointed out that China should establish a sound traceability chain for natural gas calorific value determination, have a reference (standard) device for the direct measurement of calorific value, and ensure the authority and independence of the quantity magnitude transmitting and traceability functions. Some suggestions are presented for legalized metrology and reference level (0) calorimeter and becoming a legal (natural gas) calorific metering monitoring organization.
