本文通过分析3个能耗标准,指出其用于计算煤制天然气项目能效的主要差异。针对某煤制天然气项目按照3个标准实际计算了项目能效数据。对3个标准计算得到的能效数据的差异进行了分析,由此提出针对煤制天然气项目应该规定能效的计算方法和能量折算系数的取值的建议。
By analyzing the three energy consumption standards, the paper points out the main differences between the two models in calculating the energy efficiency of coal-to-natural gas projects. For a certain coal-based natural gas project, the energy efficiency data of the project were calculated according to three criteria. The differences of the energy efficiency data calculated by the three standards are analyzed, and the suggestion of calculating the energy efficiency and the value of the energy conversion coefficient for the coal-to-natural gas project is proposed.
