Furnace for incinerating refuse - has preheated air passed into combustion chamber in opposite direction to combustion gas contg. particles

摘要

The combustion chamber has at least two orifices the first to permit unburned refuse to be loaded the second orifice to permit combustion gases to leave the combustion chamber. A first source of air effects burning of refuse whereby combustion gases, including unburned particles of refuse suspended therein are created and directed toward the second orifice. A second source of air heating means connected to it and to the combustion chamber in close proximity to the second orifice and formed to heat air from the second source. Heated air from the second source is directed into combustion chamber in a direction opposite to the direction along which the combustion gases and suspended particles, from the first combustion, are moving toward the second orifice to effect a second burning of the suspended particles with a minimum loss of heat resulting from the introduction of the second air.
