摘    要:介绍一种新型自动可调式煤粉分配装置,在风扇磨煤机直吹式制粉系统中的应用情况。通过大量的工业试验表明:新型自动可调叶栅煤粉分配器应用于国产670t/h锅炉中,能在运行中对空气和煤粉分配进行了,实现了风粉分配由不可控制到有效控制。由于燃料在炉内燃烧被分为过浓燃烧和过淡燃烧两部分,能有效降低NOx排放量,同时机械不完全燃烧损失也有较大下降,有效地提高了锅炉机组的热效率。

关 键 词:锅炉 制粉系统 自动煤粉分配器 磨煤机

Abstract:This paper proposes a new type automatic adjustable pulverized coal distributor (AAPCD) and mainly introduces the stable burning principle of this distributor and it's application in the direct|fired system in boilers with fan mills. The results show that being applied in domestic lignite boiler of 670 t/h, this AAPCD can adjust the distribution of the air and coal powder when the boiler is running; achieve effective control of distribution of them. Because the combustion of the fuel is divided into two parts|over dense combustion and over sparse combustion in boiler, the emission of NOx is reduced effective, the unburned carbon loss is fall. So it effectively increases the thermal efficiency.
Keywords:dense/sparse combustion  low pollute  distributor
