METHOD AND DEVICE FOR POWER GENERATION FROM WASTE COMBUSTION USING PART OF TERTIARY AIR Russian patent published in 2009 - IPC F23G7/12 F23G5/27 F23G5/20 C04B7/43 

FIELD: heating.

SUBSTANCE: invention relates to waste processing industry. The device for power production from waste combustion contains calciner and tertiary air supply channel. It includes one or more combustion chambers representing calciner in tertiary air supply channel. In addition, the first channel is provided with a water-cooled retainer that can be opened to retain wastes in combustion chamber until they are burnt out completely by using part of tertiary air. The above water-cooled retainer makes the combustion gases and air flowing through it. In addition, the device is provided with one or more supply units. Each of them is linked with the combustion chamber to supply wastes to combustion chamber. The power generation method from waste combustion using hot tertiary air at the temperature from 650°C to 900°C to be used in rotating furnaces includes: waste combustion in combustion chamber made in tertiary air supply channel. If part of tertiary air is used, the wastes are retained during 80 to 120 seconds ensuring complete combustion of wastes and discharge of hot combustion gases to tertiary air channel. The remaining waste material is unloaded to tertiary air channel and included into cement clinker.

EFFECT: simple device and reduced consumption of oil coke.
