关于煤炭发热量表达形式的探讨

Discussion on Expression Form for Heat Value of Coal

针对用户对煤炭发热量理解方面存在的问题 ,为了更科学地评价煤炭发热量 ,提出了标准态和生产态的概念 ,即标准收到基低位发热量、标准空气干燥基高位发热量、标准空气干燥基低位发热量和生产态收到基低位发热量 ,认为用标准收到基低位发热量Q0net,ar和生产态收到基低位发热量Q net,ar来评价煤炭质量比较合理。

Countering to the problems confronted from customers' understanding on the heat value of coal and for more scientific evaluation of coal,a concept of standard condition and production condition was given,i.e.,standard net heat value on as received base,gross heat value on air dried base,standard net heat value on air dried base,and net heat value on as received base in production condition. The standard net heat value on as received base Q o net,ar and net heat value on as received base in production condition Q * net,ar are considered to be reasonable for coal quality evaluation.
