WASTE HEAT RECOVERY INCINERATOR USING COMBUSTIBLE WASTE AS FUEL

摘要

Disclosed is a waste heat recovery incinerator using combustible waste as fuel which can: extend service life by protecting a combustion plate and a second oxygen support pipe provided in a combustion chamber from thermal deformation and corrosion by high temperature heat and the combustion gases of the combustion chamber, prevent endurance reduction resulting from foreign materials accumulated on the interior wall of the combustion chamber, and minimize harmful materials included in exhaust gas by inducing perfect combustion of combustion gases generated during combustion of fuel, thereby preventing air pollution. In the present invention, the waste heat recovery incinerator using combustible waste as fuel comprises the combustion chamber which is formed by surrounding walls of fire- and heat-proof material and the combustion plate which is installed to rotate on the bottom of the combustion chamber and burns fuel placed thereon. The combustion plate comprises: a conical rotating plate of alloy steel material in which plural spray nozzles spraying combustion air in a specific direction are projected from the upper surface, a rotary shaft which is connected to the lower center of the rotating plate to support rotation of the rotating plate, an air manifold which is arranged under the rotating plate in order to supply combustion air to the rotating plate, and a fire- and heat-proof cover member which covers from the top of the rotating plate to the projecting height of the spray nozzles in order to prevent the upper surface of the rotating plate from being exposed and the spray nozzles from protruding toward the combustion chamber.
