PURPOSE: A solid fuel boiler is provided to improve an operational efficiency because an external air is flew downward along an air supply pipe and heat-exchanged with an ascending combustion gas. CONSTITUTION: A solid fuel boiler(100) comprises a firebox member(190), a flue member(130), a fuel supply member(160), primary and secondary burning members, a boiler fuel feed member(140), a fuel distributing member(150), and a firebox fuel supply member(160). The flue member exhausts combustion gases created inside of the firebox member in the combustion of the solid fuel to outside. An air feed member comprises an air supply pipe(121) and a blower(120). An air feed member is formed along a longitudinal direction of the flue member in the flue member. The blower supplies the external air through the air supply pipe to the firebox member. The primary and secondary combustion members are arranged in the firebox member. The primary combustion member burns the solid fuel and forms the primary combustion gas. The secondary combustion member heats the primary combustion gas. The boiler fuel feed member supplies the solid fuel from outside to the inside of the boiler case(110). The fuel distributing member distributes the solid fuel of the boiler case to the firebox member. The firebox fuel supply member supplies the distributed solid fuel to the firebox member. |
