如图1所示，一种环保型煤炭锅炉，包括炉体1，炉体1优选直立的圆柱状炉体，炉体1内由上至下顺次设有加热室11、燃烧室12和排渣室13，加热室11和燃烧室12间通过导热板2隔断，导热板2优选氧化铝陶瓷板结构，为了进一步提高导热板2的导热效率，导热板2上均匀设有多个导热通孔，以将燃烧室12内煤炭燃烧的热量快速传递至加热室11内，加热室11内设有水箱6，水箱6放置在导热板2上，水箱6箱壁顶部设有第一进水口61，其底部设有出水口63，第一进水口61和出水口63分别向外穿出炉体1设置，第一进水口61外接低温水源。炉体1的进料口15即煤炭入口设置在燃烧室12对应炉体侧壁上，炉体1的排渣口14设置在炉底处，所述燃烧室12和排渣室13间设有炉篦3。如图4所示，炉篦3包括固定环31及该固定环31内均匀布置的条板32，每两个条板32间留有供煤渣掉落 的间隙。所述排渣室13内紧贴炉壁下部盘绕有换热器4，该换热器4进水口向外穿出炉体1设置，本实施例中，换热器4进水口对应设置的进水管41旁接在水箱6的第一进水口61处，通过该第一进水口61同时向水箱6和换热器4内进水。换热器4出水口穿出炉体1后竖直向上连通有出水管42，所述出水管42顶端的出口端向内穿入炉体1后和水箱6箱壁顶部设置的第二进水口62连通。本实施例工作原理为：炉篦3上的煤炭燃烧，热量经过导热板2传递给水箱6，对水箱6内水加热，热水经过水箱6的出水口63输出。同时，煤炭燃烧后煤渣掉落至排渣室13内，该掉落的煤渣和换热器4热交换，对换热器4内流通的低温水进行加热，换热器4内水热交换后升温，并通过出水管42排至水箱6内。
本实施例中，所述排渣室13内设有吹风管7，吹风管7通过吊架8固定吊装在炉篦3上，吹风管7为和炉体1同心设置的环形管结构，吹风管7具体结构如图3所示，其一端开放为进风口端，其另一端封闭，吹风管7进风口端穿出炉体1后连接有风机，该吹风管7管壁内圈中上部位置处倾斜向上开设有多个出风口71。通过出风口71对炉篦3上的煤炭吹风作业，保证煤炭燃烧需要的氧气，使煤炭充分燃烧，提高供热效率。
本实施例中，为了防止由炉篦3掉落的煤渣落至出风口71内，所述排渣室13内在吹风管7上方位置处设置有环状挡板9，如图2所示，环状挡板9和多个出风口71对应设置，环状挡板9防止煤渣落至出风口71内。优选的，所述环状挡板9为倒置锥形板结构，见 图5所示，也就是环状挡板9整体为开口朝上的喇叭形结构。该结构防止掉落在环状挡板9上的煤渣出现堆积现象，也就是该结构保证掉落在环状挡板9的煤渣能够快速滑落至炉底上。
本实施例中，为了进一步提高对煤渣热量的吸收和利用，所述排渣室13底面中心处设有圆锥状的导流罩5。该结构保证掉落的煤渣散落在圆锥状导流罩5四周，进一步提高其和换热器4的热交换效率，提高煤炭燃烧利用率。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
