AIR SUPPLY DEVICE IN UPPER COMBUSTION HEATERS Russian patent published in 2015 - IPC F23B60/00 F23L1/00 F23L9/02 

FIELD: heating.

SUBSTANCE: invention relates to solid fuel heaters. The air supply device in the upper combustion heaters comprises a flexible air duct, an air distributor, and a flexible element of the movement mechanism. The flexible air duct is connected with its one end to the air intake opening pipe. The air intake opening pipe is formed in the upper part of the side surface of the heater housing. The air duct is movably connected to the air distributor pipe through the hollow sleeve so that it is possible to turn the end of the air duct along the three axes when folding it into a spiral and unfolding it in the process of raising and lowering of the air distributor. The flexible element of the movement mechanism is made of heat-resistant wire and is attached to the sleeve in the centre of gravity of the air distributor and the sleeve. In the sleeve there is an opening, closed on the top by rotating plate, with the possibility of the position fixing. The air distributor comprises a plate with an opening in the centre and a pipe fixed to it above the opening.

EFFECT: technical result is the increase in effective capacity in upper combustion heaters.
