管道效率对反平衡法煤耗率指标计算的影响分析
摘要
以往计算管道效率时仅考虑散热损失且多取定值
这在反平衡法的发电机组煤耗率指标计算中显然不妥。分析了管道效率对反平衡法煤耗率指标计算的影响
提出了扣除锅炉侧工质泄漏热损失的管道效率计算方法
并通过实例进行了论证。
Abstract
The heat loss with a definite value is normally only considered in the traditional pipe efficiency calculation.But it is considered not appropriate for the calculation of power generating unit coal consumption index by using the anti-balance method.This paper makes an analysis on the influence of different pipe efficiency definition methods on the anti-balance coal consumption index calculation.It puts forward a pipe efficiency calculation method that deducts heat loss by leakages from boiler side.And some examples are presented.
