ROTARY INCLINED FURNACE Russian patent published in 2017 - IPC F27B7/00 

FIELD: technological processes; furnaces and ovens.

SUBSTANCE: invention relates to a rotary inclined furnace for processing aluminium scrap. Furnace comprises a lined body with a support ring, which rests on two rollers, a burner shield with a gas injection burner fixed on it with eleven mixers, a turning lined bowl with two lined chutes, a drive of the furnace rotation and a burner shield supply-discharge drive. Lined body has a heat-insulating layer consisting of a heat-insulating glass-fibre mullite silica felt and a layer of a chamotte lightweight material, which is packed with a layer of lining from a mullite silica ramming mass with a crust of slag lining. Burner includes an air flow rate control device, is installed with the inclination of 20° to the axis of the lined body with the possibility to feed gas to the burner through a pipe welded to a bracket secured on the rotary column. Furnace has a mounted on a trolley rotary lined bowl with two lined chutes, herewith one of the two lined chutes has on its bottom a chute attached thereto, which can move under the bottom of the upper one for increasing or decreasing the length of the mated chutes, the trolley moves along rails toward the lined body and backward by means of an electric drive, a rotary frame in the working position resting on the front and the rear supports of the rotary frame, the furnace can operate on both natural and artificial draft with a two-stage dust-gas cleaning plant for obtaining an ecologically clean process.

EFFECT: provided is longer life of the furnace, reduced heat losses and harmful emissions into the atmosphere.
