SELF-CONTAINED HEATING SYSTEM OF WATER TO BE USED IN CONSUMPTION SYSTEM, MAINLY OF HEATING AND/OR HOT WATER SUPPLY Russian patent published in 2012 - IPC F24D3/00 

FIELD: power industry.

SUBSTANCE: self-sustained water heating system includes heat accumulator (4) provided with heat accumulating body (HAB) (5) enclosed in housing (7) and equipped with heaters (8), consumption system (9), circulating pump (10) and expansion tank (11), which are interconnected with heat carrier circulation circuit (1) having "straight" (2) and "return" (3) pipelines (2, 3). System is equipped with hydraulically open heat exchanger - condenser (12) connected to "return" pipeline (3) in the section downstream of in-series located circulating pump (10) and throttle (13), and the other end is connected to "straight" pipeline (2) on the section upstream of branch pipe (14) to tank (11). Inlet connection pipe (17) of water heater - steam generator (15) is introduced to cavity (16) for water heating and steam generation, and the other end is connected to "return" pipeline (3) in the section between pump (10) and throttle (13). One end of outlet connection pipe (18) of water heater - steam generator (15) is introduced to cavity (16) so that its face is located at distance (S₁) from lower end of inner cavity (16), and the other end is introduced to heat exchanger - condenser (12) with annular gap (S₂) so that its face is located at distance (S₃) from lower wall of heat exchanger - condenser (12).

EFFECT: improving the efficiency of heat exchange processes between heat carrier and heating medium.
