经过改造后的炉拱,在实际运衍中观测发现,改造效果良好,燃料人炉后距煤闸板0.3MRP着火,火床燃烧强烈,火焰充满度好,旋转强烈。由于前拱降低,后拱加长,拱间形成的喉口间距由原来的2cm左右缩小到1cm。加强了该处的气流扰动混合,重新组织了气流,强化了炉内燃烧,有效的提高了前拱区和整个炉膛的温度,使其达到1400℃以上,改善了燃料的着火条件。煤着火点的提前,炉膛温度的提高,使灰渣含碳量明显减少。烟气的旋流混合又加强了烟气中焦炭粒子的分离,使之落在火床上和新燃料层进一步燃尽。强烈的烟气旋流还使烟气中的CO、H2、CH4等可燃气体充分燃烧,从而提高了锅炉的热效率4%以上。同时也提高了锅炉出力,满足了生产用汽的需要,减轻了环境污染,扩大了燃煤品种的适应范围。2.合理的送风与调节在链条炉、振动炉、往复炉中,根据燃烧过程的不同特点,合理的送风,对于促进炉内燃烧是很重要的。如在链条炉中,燃料随炉排不停地运动,依次发生着火、燃烧、燃尽各阶段。燃烧是沿炉排长度方向分阶段、分区进行的,所以沿炉排长度方向所需的空气量也就不同。在炉排头部的预热区和尾部燃尽阶段,空气需要量小；在炉排中部的燃烧阶段,空气需要量大。根据这一特点,必须采用分段送风,以满足燃烧的需要。目前国内生产的锅炉虽然都考虑到这一特性,采用了分段风室,并装有调节风门。但据调查,不少单位在实际运行中没有按照燃烧特性进行风量调节,从而使燃烧所需要的空气量与实际供风量没有很好地配合,使不完全燃烧损失增大。因此
