HOT-WATER BOILER Russian patent published in 2016 - IPC F24H1/12 

FIELD: heating.

SUBSTANCE: invention relates to heat supply systems of industrial and residential buildings. Boiler includes cylindrical housing with furnace and coaxial with it convection chamber. Furnace and convection chamber are arranged in series in housing of boiler, rigidly attached to base. Water-cooled heating surface is made single for whole length. Heat exchange unit of convection chamber is arranged in form of single structure and is arranged in cavity of convection chamber confined by screening surface heating, with possibility of reciprocal movement in it, and its detachment in vertical diametral plane, for which contains pair of parallel collectors made over its entire length, in its upper and lower parts on both sides of connector plane. Spreader with dissecting cone and connected with tubular element, coaxial longitudinal axis of boiler. "Cleave" cone surface facing furnace is made in form of hyperboloid of revolution. In volume of heat exchange unit of convection chamber there are two cylindrical shells, coaxial to each other and longitudinal axis of boiler, made of two symmetric halves to tight joint heat exchange unit. Heat insulation of the boiler has connector at joint of cylindrical shell and end parts that make gas tight boiler housing.

EFFECT: using invention reduces the cost of production of boiler, higher efficiency and repairability.
