Abrégé

The present invention relates to an air-cooled combustion furnace system which effectively operates a combustion furnace generating heat energy capable of operating a boiler by burning a solid fuel so as to optimize thermal efficiency. The air-cooled combustion furnace system according to the present invention includes: a combustion body section (100), which is provided with a hopper allowing a solid fuel (10) to be fed into same and which forms a combustion space so that the solid fuel (10) fed into same through the hopper (150) can produce heat energy while being combusted; a cooling unit (200), which is integrally formed on the outer surface of the combustion body section (100), is partitioned in the vertical direction so as to form multiple layers, and cools the combustion body section (100) by distributing and injecting air in each of the layers; a negative pressure induction unit (300), which is connected to the upper part of the combustion body section (100), takes in air fed into the combustion body section (100) by the cooling unit (200), and allows a negative pressure to be formed in the combustion body section (100); a fuel supply unit (400) that is formed so as to be connected from the outside to the inside of the combustion body section (100) so as to supply the solid fuel (10) into the combustion body section (100); a grate section (500), which is provided with a grate (510) formed within the combustion body section (100) and which forms the bottom surface of the combustion body section (100) while supporting the solid fuel (10) during the combustion of the solid fuel (10), and which has multiple grate pieces (512) being coupled with each other therein, and which allows the solid fuel (10) to be mounted for combustion on the upper surface thereof; and a clinker removal unit (600), which removes clinkers (30) which are generated during the combustion of the solid fuel (10) in the grate section (500).
