Abstract

The invention discloses an air heat preservation hot cyclone boiler, the fuel of which enters the main combustion chamber in the inner water jacket from the fuel inlet, and explodes to the surroundings under the action of the central exhaust hole, and then is heated by the heat cyclone action of the peripheral exhaust hole. Burning down, the flame is in a whirlwind shape, and the oxygen is sufficient, and the combustion is complete, then most of the soot slowly falls into the soot bin, and then the lower water inlet tank absorbs the remaining heat, and the flue gas enters the smoke collecting bin from around the connecting pipe at the bottom, and then The whirlwind flame blown out from the flue gas ignition port ignites combustible gases such as carbon monoxide in the flue gas. The heat is absorbed by the inner water jacket and the middle water jacket. The flue gas then enters the smoke exhaust chamber, and the residual heat is absorbed by the outer water jacket and the air insulation jacket. Finally, the dust-free smoke is discharged from the smoke exhaust port of the smoke exhaust bin at a temperature equivalent to the water temperature or air temperature. The fuel of the present invention burns thoroughly, has high utilization rate of heat energy, no residual heat is emitted, does not need heat-insulating material as a heat-insulation layer, saves cost, is energy-saving and environment-friendly, and is convenient for dust removal and material feeding.
