Abstract
This invention discloses a method and apparatus for heat recovery so constructed that in the process of supplying an oxidizing agent through an oxidizing agent supply path into the main body of a combustion apparatus and discharging a hot exhaust gas of combustion from the interior of the main body of the combustion apparatus, the oxidizing agent and the exhaust gas are caused to flow through a gas-pervious regenerating member formed in a lateral wall of the main body of the combustion apparatus and the area for passing the oxidizing agent in the regenerating part heated by the exhaust gas is changed along the course of time. Since the regenerating member is stationary and the oxidizing agent supply path is movable, the regenerating member itself admits of dimensional increase and the combustion apparatus enjoys a high capacity for combustion, permits a reduction in the interval between the time the combustion is started and the time the temperature of combustion reaches a prescribed level, and enables the combustion to proceed in a range of high temperature. The apparatus, therefore, is simple in structure and brings about generous energy saving, ensures high operational safety, and features a long service life.
