HOT-WATER BOILER Russian patent published in 2016 - IPC F24H1/00 

FIELD: energy.

SUBSTANCE: invention relates to power engineering and can be used in heat supply systems of industrial and residential buildings. Boiler includes housing with furnace and convection chamber coaxial with it. At forefront of furnace burner is installed, and at rear edge is flue gases spreader. Parallel to the surface of the furnace there is a water-cooled heating surface. Hot-water boiler is detachable in vertical longitudinal plane, upper and lower headers, placed on one side from plane in section of the furnace are arc-shaped tubes that make furnace screens, and heating surface of convection chamber comprises transverse streaming pipe bunches. Heat insulation of boiler has connector at joint halves of boiler housing, equipped with gastight metal skin from outside. In cavity of convection chamber there are two split cylindrical shells. Diameter of larger shell corresponds to diameter of slicing cone, and smaller corresponds to discharge gas channel diameter. Trailing edge of the furnace is communicated with annular gas collector by gas tap pipes arranged on both sides of vertical diametral plane of boiler, in lined bottom.

EFFECT: technical result is reduction of costs, higher efficiency and repairability.
