description FIELD: mining industry. SUBSTANCE: device has air heater 3, heat-carrier source 4, chamber 5 for mixing smoke gases with outside atmospheric air made in the form of labyrinth with outside air flow regulator 12, gas duct 6 which connects labyrinth with air heater 3. Installed in gas duct 6 is shutter 13 with power drive unit 30. Equipment for automatic regulation of air temperature in hole is made up of controllable regulators 20, 21 for gas (fuel) and blast air flow rates provided with power drive units 22, 23, regulating units 18, 19 with comparing unit 17 connected with temperature sensors 15, 16 of air in hole and outside. Installed in air heater passage are gas analyzers 24 which are electrically connected with drive unit 30 of shutter 14 and with drive units 22, 23 of regulators 20, 21 for rate of fuel and blast air delivery to burning device 7 or furnace 4 with fluidized bed. EFFECT: higher efficiency. 1 cl, 2 dwg øøø1
