电站锅炉低负荷稳燃燃烧器选型评述

Comments on the selection of low load stable combustion burners for utility boilers

介绍了浓淡型燃烧器、水平浓淡煤粉燃烧器、径向浓淡旋流煤粉燃烧器、双通道自稳式燃烧器、多功能船形燃烧器以及HT-NR旋流燃烧器的工作原理和性能特点;通过分析采用不同燃烧器对大中型电站锅炉直流式燃烧器及大中型对冲式电站锅炉旋流燃烧器的改造实例,确定了各种燃烧器的适用范围,为低负荷稳燃燃烧器选型提供了依据。

The working principle and performance characteristics of Dense dilute burner,horizontal Dense dilute pulverized coal burner,radial Dense dilute swirl pulverized coal burner,double channelself stabilizing burner,multifunctional ship burner and ht-nr swirl burner are introduced;By analyzing the transformation examples of once through burner of large and medium-sized utility boiler and swirl burner of large and medium-sized opposed utility boiler with different burners,the application scope of every burner is determined,which provides the basis for the selection of low load stable combustion burner.
