660MW超临界锅炉燃烧器的设计

Design For Coal Burner Of 660MW Boiler With Supercritical Spiral Waterwall

对于超临界墙式切圆燃烧大风箱结构锅炉,燃烧器采用拉开式布置方式,同时采用水平浓淡燃烧技术,实现了分级燃烧,从而使锅炉的负荷适应能力增强、能有效控制NOX的生成,对环保有利。本文就某台660MW超临界锅炉燃烧器的设计方案、布置做了简要概述。

For 660MW boiler with supercritical spiral waterwall, arrangement for coal burner adopt separate disposal, at the sane time , using level shade burning technic, make classification combustion come true . Thereby improve capability of boiler charge. , control NOX , To be beneficial to circumstance . the design and arrangement for some one coal burner of 660MW boiler with supercritical spiral waterwall are introduced in this paper.
