摘要

根据GB/T 10184—2015，构建了高炉煤气锅炉炉效计算模型，分析了高炉煤气锅炉炉效计算方法。结果表明：燃气基准的差异导致高炉煤气水分及低位发热量的计算方法不同，并列出了2种燃气基准下高炉煤气水分的计算方法及低位发热量的换算方法；提出了3种适用于高炉煤气锅炉的过量空气系数、实际烟气量及烟气中CO2含量的求解方法，并提出了适用于含煤气加热器的高炉煤气锅炉排烟温度的修正方法；GB/T 10184—2015对部分公式的计算有待于进一步探讨，并可作适当修改。

Abstract

According to GB/T10184 — 2015

the calculation model of blast furnace gas boiler efficiency is constructed

and the calculation method of blast furnace gas boiler efficiency is analyzed. The results show that the calculation methods of gas moisture content and low-level calorific value are different due to the difference of gas benchmarks.Three methods for solving the excess air coefficient

actual flue gas volume and CO2 content in the flue gas are proposed for blast furnace gas boilers

and a correction method for exhaust gas temperature of blast furnace gas boilers with gas heaters is proposed;The calculation of some formulas in the GB/T10184—2015 needs to be further discussed

and appropriate modifications can be made.
