REVERSE AERODYNAMIC HEATER WITH INCREASED LENGTH ROTOR Russian patent published in 2019 - IPC F26B23/00 F24H3/02 F24V40/00 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering, in particular for use in air heating and injection systems in recirculation heating plants, namely in wood kiln driers. Reverse aerodynamic heater with rotor comprises casing 2 with movable flaps 3, by means of which reverse of heated flow is performed without changing direction of rotor 1 rotation. Flap height is 1/4 of casing 2 diameter. Casing 2 is fixed on frame 4. Inside casing 2 there is rotor of increased length 1, having diameter of up to 350 mm, maximum length of rotor is up to 1,400 mm. Rotor comprises blades 5 having radius of bending in accordance with calculation of blades for aerodynamic heating, connected by fastening rings 7, having slots in shape of blades bending, one above, the other from below in pairs, located at distance up to 400 mm, starting and ending with end discs 8, also having slots resting on plate springs 6.

EFFECT: invention allows increasing uniformity of heated air flow along the pile length and width, reducing the flow rate and reducing electric power consumption.
