锅炉本体漏风对锅炉热效率的影响

The Influence of Boiler Air Leakage for Boiler Thermal Efficiency

锅炉本体漏风会使锅炉排烟热损失升高,锅炉热效率降低。通过锅炉热效率计算的方式来分析锅炉系统漏风对基准温度、理论烟气量及排烟温度的影响,进而分析其对锅炉热效率的影响,并针对现代大型锅炉常见漏风原因提出解决方案。

Boiler air leakage will increase the boiler heat loss due to heat in dry flue gas,reducing the boiler thermal efficiency. This article focuses on the calculating measures for boiler thermal efficiency to analyses the air leakage influence for the base temperature of boiler system and temperature of flue gas,then analyzes there impacts for the boiler thermal efficiency,and lists common leakage reason and proposes appropriate solutions to modern large-scale boiler.
