某电厂220t/h锅炉煤粉燃烧器改造设计方案

Design method of pulverized coal burner of 220t/h boiler of a power station

为提高某电厂 2 2 0t/h煤粉锅炉燃烧器低负荷稳燃能力 ,拟采用浓淡燃烧技术对该炉燃烧器进行改造 ;下层燃烧器采用水平浓淡燃烧器 ,上层燃烧器采用上下浓淡燃烧器 ;为保证低负荷时的主蒸汽温度 ,上层燃烧器为摆动式燃烧器。

To improve the low load flame stability of the pulverized coal burner of 220t/h boiler of a power station,we want to reform the boiler burner with bias pulverized coal combustion technology.From bottom to top,the below layer burner is the horizontal bias pulverized coal burner,the up layer burner is the vertical bias pulverized coal burner;to improve the steam temperature at low load,the up layer burner is the swaying burner.
