According to the present invention, a system for recovering discharged steam in a combustion apparatus comprises a fresh tank and a water supply pump. The combustion apparatus for recovering heat has a combustion tank provided with combustion air from the outside to burn solid fuel supplied by a fuel supply pipe coupled to a lower part thereof and discharges combustion gas generated by combustion of solid fuel to a boiler to recover heat. The combustion apparatus comprises a combustion chamber and a water cooling chamber. The combustion chamber has a cylindrical shape and is surrounded by an inner wall of the combustion tank to burn fuel supplied to a lower part thereof. The water cooling chamber is formed on the outer periphery of an inner wall of the combustion chamber, has a cooling water outlet for discharging cooling water and a cooling water inlet for introducing cooling water, which are formed on the upper side and lower side, respectively, to cool the inner wall of the combustion chamber by cooling water introduced through the cooling water inlet. The fresh tank allows cooling water discharged through the cooling water outlet of the cooling water chamber to be introduced and is formed using a pressure container to make cooling water at high temperature, which becomes steam in atmosphere, be saturated water to be again supplied to the water cooling chamber of the combustion apparatus. The water supply pump supplies cooling water from the fresh tank to the water cooling chamber of the combustion apparatus. According to the present invention, evaporated steam generated through continuous circulation of the cooling water of the combustion apparatus is not discharged, and the cooling water can be again circulated into the water cooling chamber. |
