摘要

对某电厂 2 2 0t/h锅炉防止水冷壁结渣的改造方案进行了炉内燃烧三维数值计算

根据计算结果对比分析了改造前后炉膛内的流动燃烧传热状况

认为改造方案切圆大小适中

气流组织合理

火焰中心始终保持在炉膛中心

有利于防止锅炉结渣和高温腐蚀

Abstract

Three dimensional numerical calculation of combustion in the furnace has been carried out for retrofitting scheme of preventing waterwall of a 200 t/h boiler from slagging in one power plant. Based on results of calculation

the flow combustion and heat transfr state in the furnace before and after retrofitting have been compared and analysed. It is considered in the scheme that the size of tangential circle to be moderate

the organization of air flow to be reasonable

the flame centre to be kept in the centre of furnace from begining to end

being beneficial for preventing the boiler from slagging and hightemperature corrosion.
