PROBLEM TO BE SOLVED: To provide a heat exchanger integrated combustion furnace capable of improving a hot-water production capability regarding a combustion furnace for combusting biomass fuel and a heat exchanger using this combustion furnace as a heat source.SOLUTION: A heat exchanger integrated combustion furnace 1 is formed by lining up a rectangular parallelepiped combustion part 2, a first heat exchange part 3 and a second heat exchange part 4 in a rectangular parallelepiped shape. In a combustion chamber 8 of the combustion part 2, upward combustion air is supplied from a through hole 11 of a bottom face plate 10, combustion air in an eccentric direction is supplied from a lower-stage air supply pipe 25 disposed in an upper portion of an inner wall surface into an axially perpendicular plane, and combustion air in an eccentric direction opposite to the lower-stage air supply pipe 25 is supplied from an upper-stage air supply pipe 26 disposed in an upper portion of the inner wall surface towards a bottom face. A disturbance of combustion air is formed in an upper portion of the combustion chamber 8 and combustion gas and combustion air are stirred, mixed and completely combusted, thereby improving heat exchange efficiency of the first heat exchange part 3 and the second heat exchange part 4. |
