Abstract
A combustion apparatus has a combustion furnace section, a free board section which is downstream of the combustion furnace section, and a post-combustion chamber which is downstream of the free board section, the post-combustion chamber being disposed at a position offset from the position directly above the free board section, wherein the apparatus is characterized in that a gas blowing structure is provided in the vicinity of the boundary between the free board section and the post-combustion chamber, the gas blowing structure having a plurality of pipes disposed parallel to each other at a predetermined spacing, each pipe being provided with a gas outlet hole for blowing a gas, for example, air, counter to the combustion gas flowing toward a discharge port. With this arrangement, when a gas is blown in from the gas blowing structure counter to the combustion gas, a large whirling flow, in which the combustion gas and the gas thus blown mix together, is generated in the free board section, so that unburnt gas and combustion air are thoroughly mixed together within the free board section, thus enabling complete combustion.
