The object of the present invention is to provide a cooling device of a combustion chamber, wherein the cooling device of a combustion chamber not only effectively prevents the overheating of a combustion chamber but also improves the heat efficiency of a boiler even while having a simple structure. To achieve this objective, the cooling device of a combustion chamber according to the present invention cools the combustion chamber by absorbing combustion heat that is emitted from the combustion chamber which has a burner for burning a mixture of combustion gas and air that is supplied from a blower. In the cooling device, the combustion chamber includes an outer wall and an inner wall thereof, which is at a distance from the outer wall of the combustion chamber in proximity to the inside of the outer wall and has a plurality of holes, wherein a space between the outer wall and the inner wall of the combustion chamber communicates with the blower. |
