摘要
在4 MW工业级热态试验平台上,研究了上斜式旋转锥解耦燃烧器燃烧生物质、煤矸石的性能.考察了一级锥转速、过量空气系数、配风等操作条件对燃料燃尽率、燃烧速率、燃烧份额的影响规律.结果表明:提高旋转锥转速和过量空气系数对燃料燃烧具有明显的促进作用;配风比对燃烧器性能具有显著影响,当一次风配比过低时,燃料不能正常燃烧.当一次风配比过高时,燃料的燃尽率、燃烧速率、未燃尽份额都比最佳配风比时有所劣化.对于本文燃用的生物质燃料,最佳配风比为一次风配比0.4～0.6.
Abstract
The performance of an upward-rotary-decoupling combustor for burning biomass and coal gangue was studied on a 4 MW industrial grade thermal test platform.The influences of operating conditions such as first stage cone speed,excess air coefficient,and air distribution on fuel burnout rate,combustion rate,and combustion fraction were investigated.The results show that increasing the rotational cone speed and excess air coefficient have a significant promoting effect on fuel combustion;the air distribution ratio has a significant impact on the performance of the burner.When the primary air ratio is too low,the fuel cannot burn normally.When the primary air ratio is too high,the burnout rate,combustion rate,and unburned fraction of the fuel all deteriorate compared to the optimal air ratio.The optimal air ratio for the biomass fuel used in this article is a primary air ratio of 0.4-0.6.
