摘要
通过比较各种不同的燃煤锅炉炉膛传热计算方法,在前苏联1973年热力计算标准中的分区段计算方法的基础上,提出一种改进算法,用于超临界锅炉炉膛传热计算。并对某600MW超临界锅炉采用改进的分区段法进行炉膛传热计算,结果与实际基本吻合。改进的分区段算法充分考虑了超临界锅炉炉膛结构和燃烧方式,可以作为超临界锅炉炉膛传热计算的有效工具。
Various heating calculation methods in coal fired boiler furnace were compared in this paper.An advanced method of calculation in sections for supercritical boiler,based on the calculation-in-sections method of the former Soviet Union boiler unit heating calculation standard methods in 1973,was proposed.Heating calculation with the advanced method was done in a 600MW class supercritical boiler furnace.The result was consistent with the real.Furnace structure and combustion way of supercritical boiler being ...
