HEAT GENERATOR AND HEAT SUPPLY SYSTEMS (VERSIONS) Russian patent published in 2003 - IPC

FIELD: heat engineering; autonomous heat supply systems. SUBSTANCE: heat generator includes furnace chamber with gas duct and consumer, fuel supply unit and water heating and gas-and- steam preparation system. Heat generator is made in form of O-shaped steam-and-gas chamber with spherical bottom or with bottom having another form which is divided into liquid and steam-and-gas cavities; it is mounted above furnace chamber wherefrom combustion products of any fuel are admitted to steam-and-gas cavity provided with device for cleaning them, mixing and reducing their temperature to required level; it is made in form of row of chambers formed by guide partitions; steam- and-gas mixture changes its direction, velocity and pressure and gets in contact with liquid which is necessary for cleaning and reducing temperature; ash is removed from bottom portion of steam-and-gas chamber by blowing; waste gas utilizer is made in form of washer for scrubbing the steam-and-gas mixture with feed liquid delivered to smoke stack after consumer which is later used together with condensate for make-up of steam-and-gas chamber to level of lower edges of guide partitions. Heat supply system includes steam-and-gas chamber made in form of hot-water boiler equipped with furnace chamber which is connected with gas duct, pipe lines for natural circulation of water with heating appliances, expansion reservoir and air receiver. System is made in form of heat generator for generation of steam-and-gas mixture; it is provided with gas duct, shut-off and regulating unit connected with heat exchanger of autonomous heat supply system with natural circulation of water wherefrom used steam-and-gas mixture and condensate flow to smoke stack made in parallel with gas duct; then, flue gases are exhausted to atmosphere and condensate is used for make-up of steam-and-gas chamber divided into liquid and steam-and-gas cavities; this chamber receives combustion products from furnace chamber for cleaning and mixing them and reducing their temperature to required level; water preheater is last in gas duct which is closed with gate. Heat supply system for floor heating method includes heat source, supply, distributing and heating passages inclined towards receiving passage and gate; it is made in form of heat generator for generation of steam-and-gas mixture with gas duct connected through shut-off and regulating unit with distributing passage and with receiving passage through heating passages wherefrom used steam-and-gas mixture and its condensate enter smoke stack which is parallel to gas duct; then, flue gases are exhausted to atmosphere and condensate is used for make-up of steam-and-gas chamber divided into liquid and steam-and-gas cavity receiving combustion products for cleaning and mixing them and reducing their temperature to required level. Gas duct is closed with gate. EFFECT: enhanced efficiency. 18 cl, 12 dwg
