The device relates to the field of heat engineering, in particular to the design of a heat engineering device intended for heating and steam generation, and can be used for the equipment of baths and saunas. The device allows to obtain various combinations of temperature and humidity.;The main elements of the device are: a metal casing, shielding hard infrared radiation, in the form of a horizontally oriented cylinder with a wave-like notch on top, inside of which, according to the shape of the notch, heat-accumulating elements are laid; a fire chamber, the upper plate of which has a diameter in the form of a trapezoid curved upward, forming additional stiffening ribs with its sides, allowing it to withstand considerable loads without deformation, a boiler nozzle and two symmetrically arranged rows of narrow longitudinal convection apertures; fuel channel in the form of a horizontal parallelepiped or a pipe of circular cross section, the length of which can vary; the door of the fuel channel in the form of a rectangular frame with a frame in the form of a flat frame, curved outward,;Technical result: increase in the area of heat transfer of the device and increase the efficiency of the device due to the high efficiency and level of convection of hot air without increasing the size and fuel consumption. 1 il.
