A combustion apparatus for a granular solid fuel, comprising a plurality of horizontal cylindrical combustion chambers serially connected in their axial direction, partitions interposed between the combustion chambers, communication holes pierced through the partitions for passing the combustion gas. To the combustion chambers, air is delivered in directions to cause the gas to flow in a swirled state, allow the granular fuel to be burnt as agitated and fluidized within the upstream combustion chamber, and forward the gas in a swirled state from the upstream to the downstream combustion chamber. The combusted gas, on reaching the extreme downstream combustion chamber is drawn out by means of a gas delivery pipe having one end thereof communicating with the combustion chamber.
