摘要
以化石燃料的实际反应过程为研究对象,根据实际燃烧过程模型,推导了含C、H、O、N、S等多种元素成分的基于燃料高位热值的化学计算式,对我国部分地区煤种的化学进行了计算,并将计算结果与以纯物质为模型的信沢寅男和范良政方法的计算结果进行了比较.结果表明:采用所提出的基于燃料高位热值的化学计算方法得到的计算值与两学者计算值的误差较小.
Taking the actual reaction process of fossil fuel as an object of study, a calculation formula of chemical exergy was derived for fuels containing a number of elements, such as C, H, O, N, S, etc. , based on actual combustion process models and high heating values. With the formula, chemical exergy of some domestic coals was calculated and compared with that of overseas calculation results based on models for pure substance. Results show that the calculated values of chemical exergy obtained by the newly derived formula based on high heating values agree well with that of other researchers.
