A method for heating water with hot substances formed at fuel burning by means of a metal part includes fuel combustion, heating substances formed at fuel burning with heat of burning fuel, supply of hot substances to inner volume of the metal part installed in given volume filled with water, this with its outer surface is in contact with water, to convection channels in the inner volume of the metal part intended for passage of hot substances formed at fuel burning and to space between the convection channels with transfer of heat to water, with following removal of hot substances formed at fuel burning from the inner volume of the metal part. In the inner volume of the metal part uniform distribution of velocity of motion of hot substances generated at fuel burning is formed at the area of cross section of the metal part by means of convection channels that have in the cross section of the metal part minimal radius of the concave surface at the side of hot substances within 3-30 mm. Decrease of consumption of fuel is achieved. |
