Heating gas apparatus has furnace with gas burner, body-heat exchanger with inlet and outlet branch pipes and water jacket inside which heat exchange cavity is placed, this is formed with vertical walls with spherical depressions to inside of the cavity at opposite sides, rows of cross pipes placed inside the cavity with shift, those connect to each other opposite parts of water jacket, gas channel with smoke channel. The pipes are arranged at angle 1-3° with respect to cross axis of heat exchange cavity that belongs to vertical plane, and are directed to output branch pipe. At the outer surface of the pipes at whole length of those depression is provided, and depressions of heat exchange cavity are arranged with radius not larger than radius of the pipes and placed in places of largest distance of pipes from walls of heat exchange cavity. Depressions on the pipes are arranged as threading with angle of elevation to opposite side from inlet branch pipe, either as long rifles. Such implementation of heating gas apparatus provides intensification of turbulization of heat flows, this increases intensification of heat exchange. |
