【摘要】 水煤浆作为经济型清洁燃料引起了人们的长期关注．水煤浆偏置射流预燃室具有对浆种适应性强，稳燃性能好等特点．本文对偏置射流预燃室稳定燃烧水煤浆的原理进行了探讨，并对该燃烧技术用于处理造纸黑液的研究情况作了介绍．结果表明，采用低压多级雾化喷嘴对水煤浆进行雾化，形成的雾炬和偏置射流预燃室的流场有良好的匹配，在预燃室内形成大尺度的回流区，有利于水煤浆的点火、稳燃和消除灰渣．更多还原

【Abstract】 Coal-Water Slurry(CWS) has long been attractive due to its low price and clean property. Investigations on the flame-stabilization mechanism of the nonsymmetrical-jet precombustor were carried out. Also presented was application of CWS combustion technology in handling of black liquor in pulp & paper industry. The results turned out that the spray of the low-pressure multi-stage nozzle well matches the flow field in the nonsymmetrical-jet precombustor. The large-scale recirculating zone generated in the precombustor is favorable for CWS ignition, stable combustion and removal of ash.更多还原
