摘要

当锅炉主要运行参数偏离目标值时

会引起锅炉热效率的下降

导致机组发电煤耗升高。为此

分析了煤气锅炉热效率的计算要点

并提出了适用于煤气锅炉的煤耗偏差分析模型

给出了锅炉运行过程中排烟温度、排烟氧量、排烟CO含量变化时的发电煤耗偏差计算模型。实际计算结果表明

该模型能够较准确地计算出锅炉主要运行参数偏离目标值所引起的煤耗偏差

可为机组的优化运行提供数据依据。

Abstract

If main operation parameters deviate from the target value

the boiler thermal efficiency will decrease and the unit coal consumption will rise.Thus

the key points in calculating gas boiler thermal efficiency was analyzed

and the energy-loss analysis model which is suitable for gas boilers was put forward.Taking a 220t/h blast furnace gas-fired boiler as the research object

the established model was adopted to calculate the coal consumption deviation resulted from the boiler operation parameters' variation

like the exhaust temperature

the oxygen content in exhaust

CO concentration in exhaust and so on.The results show this model can obtain the coal consumption deviation accurately

which provides a guidance for boiler optimization operation.
