一种燃烧换热装置，包括：燃烧室、燃气烧嘴、换热器、烟道接头、烧嘴砖；
在燃烧室内中间底部设有一个下凹的容置部，换热器安装在燃烧室中，换热器的底部嵌入燃烧室内的容置部；
换能器顶部设有冷空气进口和热空气出口；换能器的顶部露出燃烧室；换能器与燃烧室顶部连接处密封；
在燃烧室一侧侧壁上安装烧嘴砖；烧嘴砖内具有朝向燃烧室内部的喇叭口；燃气烧嘴安装在燃烧室侧壁外侧，燃气烧嘴的火焰口对接烧嘴砖的喇叭口后端；
燃气烧嘴上具有空气接口和燃气接口，用于分别连接热空气管道和燃气管道；热空气管道的一端连接在换热器的热空气出口，另一端连接燃气烧嘴上的空气接口；
在燃烧室背离烧嘴砖的另一侧顶部连接烟道接头。
进一步地，燃气烧嘴的空气接口和燃气接口上均设有阀门。
进一步地，燃气烧嘴设有两个，相应地，烧嘴砖也设有两块。
本发明的优点在于：
1）适应环保潮流，产生的烟气污染小。
2）较大的提高了热效率，节约能源。
