空气分级燃烧技术中两级燃尽风技术试验研究

Research of Two-Section Overfire Air Technology Test in the Air Staged Combustion Technology

本文以神木烟煤和阳泉贫煤为试验对象,在一维火焰炉上对其进行了空气分级燃烧技术模拟试验研究。试验结果表明,与通常的空气分级技术相比较,燃尽风分两股送入炉内不仅能有效降低NOx的排放量,还能很好的降低飞灰可燃物含量,取得更佳的脱硝效果和燃尽效果。

The Shenmu bituminous and Yangquan lean coal are tested, the research of air stageo combustion technology tes is executed in the one - dimensional flam furnace. The test research indi- cates that, compare with the common air staged combustion technology, overfire air into the furnace in two sections can ont only reduce the NOx emission, but also reduce the fly ash combustible content, so the denitration and overfire effect.
