北京煤炭科学院煤化所利用工业分析测值和不同地区的碳氢值配合导出了计算各种煤的发热量的计算公式,此公式精度高于外国其他公式。但是,根据煤化所的公式计算结果分析,当H~r(％)值在2.5～3.0,K_0=8350时,所得结果误差较小;而当H~r=3.0～3.5(％),K_0=8450时,所得计算结果 Beijing Institute of Coal Chemical Industry Institute of coal use of industrial analysis and measurement of hydrocarbon emissions in different regions with the calculation derived from the calculation of various coal calorific value formula, this formula accuracy is higher than other foreign formulas. However, according to the formula calculation results of coalification institute, the error of result is small when H ~ r (%) value is 2.5 ~ 3.0 and K_0 = 8350; when H ~ r = 3.0 ~ 3.5 8450, the results of the calculation
