【技术实现步骤摘要】
反烧热水锅炉热交换管组
本技术提供的是生物质燃料的燃烧设备,具体地说是反烧热水锅炉热交换管组。
技术介绍
目前,生物质颗粒作为锅炉的燃料,烟气污染小,排放量低,已经得到广泛地推广应用。但现在有直烧或是反烧形式,尤其是直烧形式的锅炉容易造成燃料燃烧不充分,并产生大量的不完全燃烧的烟气,不但热量利用率低,而且导致锅炉热效率低。反烧锅炉的火焰直接加热水管,通过水管与燃焰热交换使锅炉中的水加热,也存在热效率低的弊端。
技术实现思路
为了克服现有生物质燃料锅炉存在的缺点,本技术提供了反烧热水锅炉热交换管组。该热交换管组通过在锅炉内设置,管内走火,管外走水,解决锅炉热交换管组设置的技术问题。本技术解决技术问题所采用的方案是:在炉体水箱内竖直排列装有多根火管,火管下部与火道相通,上部与烟腔相通,火道与燃烧室下部相通,烟腔与排烟管相通,火道侧部设有火道清灰口,水箱上部设有出水口。燃烧室上部与燃料输送管相通,在燃料输送管内装有螺旋输送器,螺旋输送器与上料电机连接,在燃料输送管上部设有燃料斗。在燃烧室壁上设有进气口,下部设有清灰门,在排烟管上装有引风机。炉体坐在炉座上。积极效果,本技术通过燃烧室不完全燃烧的烟气进入热交换管继续燃烧,对热交换管外部的水进行加热,其优点在于,燃料反烧,无烟气直接排放;热交换管为火管,与管外水热交换面积大,热交换效率高。锅炉整体具有较高的燃烧效率。适宜作为生物质颗粒燃料反烧热水锅炉热交换管组使用。附图说明图1为本技术结构图图中,1.燃料斗,2.上料电机,3.螺旋输送器,4.燃烧室,5.清灰门,6.火道,7.火管,8.炉体,9.烟腔,10.排烟管,11. ...
