PURPOSE: A solid fuel boiler is provided to form vortex in combustion gas flowing in a connection pipe for improving heat exchange efficiency by inserting a pipe insertion member into a connection pipe. CONSTITUTION: A solid fuel boiler(100) comprises a fire chamber(140), an upper case(110), a flue member(170), connection pipes(150, 155), and a pipe insertion member(200). The fire chamber is located in the upper case and accommodates water in the upper case. Combustion gas is exhausted through the flue member. The connection pipe guides combustion gas to the flue member. The pipe insertion member comprises a connection shaft, a turbulence forming unit, and a combustion sediment removing unit. A vortex forming part forms vortex in combustion gas. The combustion sediment removing unit is extended to the inner wall of the connection pipe. When the connection shaft is moved up and down along the connection pipe by external force, a sediment removing unit removes the sediment on the inner wall of the connection pipe. |
