Description

一种燃用生物质秸秆成型燃料的常压热水锅炉
所属技术领域
[0001 ] 本实用新型涉及一种锅炉,燃用生物质秸秆成型燃料的常压热水锅炉。
背景技术
[0002] 目前,现有的小型热水锅炉大都采用正烧,双层炉排,下加煤等传统方式,造成炉 排易烧损,燃烧阻力大,存在周期性,有的需要风机,飞灰率高,燃烧效率低。
发明内容
[0003] 本实用新型针对上述存在问题,提出了一种新的、正反双向进风的燃烧方式,主要 针对挥发份占70%的生物质秸秆成型燃料的燃烧,开发出的专用锅炉。
[0004] 本实用新型解决其技术问题所采用的技术方案是:在锅炉内胆(3)的上部布置错 排的水管管束(2),在锅炉中部设倒L板式换热器(12),板式换热器将炉膛隔成左右两区, 右侧布置燃料仓(5),燃料仓(5)的上部被板式换热器封死;左侧及下部是高温燃烧区,板 式换热器左、右两侧与内胆壁(3)的距离比1/3 : 2/3,板式换热器的底部距炉栅的距离为 200mm左右,燃料仓大于燃烧区,锅体内留有正向进风道(9)及反向进风道(6)两次供风通 道。
[0005] 本实用新型的有益效果是,通过上述构思将秸秆燃烧释放出的大量可燃挥发份 (烟),由反向进风强制带领可燃挥发份反向穿越火层,在高温燃烧区在正向进风的配合 下,得到彻底燃烧,达到无烟燃烧的目的。
附图说明
[0006] 图1是本实用新型的剖视图; [0007] 图2是本实用新型的俯视图。
[0008] 图中1.烟囱座,2.错排水管,3.内胆,4.加料斗,5.燃料仓,6.反向进风道,7.反 向进风,8.进风门,9.正向进风道,IO.炉栅,ll.进水口,12.板式换热器,13.清灰口, 14.出水口,15.大气管。
具体实施方式
[0009] 锅炉点燃后,从加料斗(4)向燃料仓(5)加满生物质秸秆成型燃料,在正向进风道 (9)提供一次风的作用下,生物质秸秆在炉栅上进行氧化燃烧,燃料仓(5)上方的燃料会被 加热干燥后(IO(TC _105°C )释放出挥发份(烟),由于烟囱的抽力和倒L型板式换热器的 阻挡,会使反向进风(7) (二次风)先向下,然后绕过板式换热器再向上。反向进风会带领 料层中释放出的可燃挥发份(烟)穿过高温氧化区,得到完全燃烧达到无烟燃烧效果。高 温烟气先经板式换热器的两面及内胆表面,经传导、辐射、对流换热后,烟气再沿错排的水 管外壁流过、碰撞、冲刷管壁延长了换热时间,增加了换热面积,降低了排烟温度。正反向进 风的动力均来自烟囱的抽力,不使用动力,静态燃烧,既节能又环保。
