锅炉烟道漏风对对流受热面传热的影响分析

Analysis of Air Leakage of Boiler Convection Heating Surface

在理论分析的基础上结合实例说明了烟道漏风对烟气温度、对流放热系数、辐射放热系数、对流传热系数、对流传热量的影响,为减轻锅炉漏风的危害提供了理论依据。具体数据通过对某台再热煤粉锅炉的热力计算得到。

Based on theoretical analysis, this paper presents the impact of air-leakage on gas temperature, convection heat transfer, radiation heat transfer with examples. It will provide theoretic reference for avoiding boiler air leakage. Specific data was given by heat calculative analysis of reheat pulverized coal fired boiler.
