A heat generator with wick-feed burner includes a body in the lower section of which fuel vessel with wick-feed burner is provided, over that primary combustion chamber and afterburning chamber are placed, wick made of fire-resistant material is placed at the bottom of the fuel vessel, and oxidizer is supplied not less than through two nozzles placed at the side surface of the body and fed by means of fan, at that the wick is made flat, and over the fuel vessel a three-stage air heater is additionally placed, its first stage receives heat from gases that go out from the afterburning chamber, the second one is heated by the gases from afterburning chamber, and the third one with flame of the primary combustion chamber. The first and the second stages of the air heater are arranged as cylinders placed one into another, and the third stage is separated from the primary combustion chamber by flat metal surface formed with depressions at the side of the primary combustion chamber, the surface is fixed on telescopic insert with possibility of change of the distance from the upper end of the wick, and in the center of the wick a cylindrical heat-conductive insert is placed, its diameter is smaller compared to the inner diameter of the afterburning chamber, and the height is not smaller than the thickness of the wick. |
