Claims

[Scope of utility model registration request]

(1) Solid fuel in which solid fuel is deposited on a grate in the furnace main body, and combustion air is supplied from an air supply chamber formed below the grate toward the deposited layer of solid fuel. In the combustion apparatus described above, an air supply pipe is connected to the air supply chamber of the furnace main body, and the open end of the air supply pipe facing the inner surface of the air supply chamber is provided with 1. A solid fuel combustion device characterized in that an air guide member is provided in series to guide combustion air diagonally downward within an air supply chamber.

(2) A circulation pipe for circulating a part of the combustion exhaust gas discharged from the upper part of the furnace body is connected to the air supply chamber, and the open end of this circulation pipe facing the inner surface of the air supply * The solid fuel combustion apparatus according to claim 1, further comprising a combustion exhaust gas guide member that guides the combustion exhaust gas obliquely downward within the air supply chamber.

(3) A circulation pipe for circulating a part of the combustion exhaust gas led out from the upper part of the furnace body is connected to the supply chamber, and the circulation pipe has an upper and lower open end facing the inner surface of the air supply chamber. Claim 1 of the utility model registration is characterized in that a pair of guide plates are fixed to each other inwardly of the air supply chamber, the guide plates being close to each other and forming a slit-like opening between the inner ends. The solid fuel combustion device described in Section 1.
