煤质分析报告与燃烧计算

Analysis report for coal properties and combustion calculations

燃烧计算所需要的工作质的碳、氢、氧、氮、硫、灰分和水分7项成分的煤质分析数据,一般的煤质分析报告提不出来。本文作了某些简化的、近似的工程处理。计算出“空气干燥基”的上述7项成分数值,用以代替常用的工作基成分,通过实例计算,发现能很好地与实际情况相符合,提示这种工程处理在实用上的可行性。

An average analysis report for coal properties may not provide the data on seven working elements and matters viz. C, H, O, N, S. ash and water necessary for combustion calculations. For this concern, the paper makes a simplified engineering approximation which allows the said seven working elements and matters to be capable of being calculated on the 'air dry basis' instead of the ordinarily applied working basis. The calculation results being consistent with pratical situation show that the engineering approximat ion in this way is applicable.
