METHOD FOR OFF-LINE HEATING OF AND HOT-WATER SUPPLY TO DWELLING HOUSE AND OFF-LINE SYSTEM FOR HEATING OF AND HOT-WATER SUPPLY TO DWELLING HOUSE Russian patent published in 2005 - IPC

FIELD: thermal engineering; off-line heating of and hot-water supply to houses and industrial buildings and structures.

SUBSTANCE: proposed method involves use of heat produced by heat-power generator by heating gas and water coolants circulating in pipelines over closed loop, starting of internal-combustion engine on source liquid or gaseous fuel, heating of coolants by engine exhaust gases and by hot water of engine cooling system, plenum ventilation of premises with hot air passed from heat-transfer apparatus, heating of premises with aid of radiators supplied with heat-carrying agent, water heating in boiler for domestic needs, and heat accumulation in heat-storage materials insulated in earth foundation under the house. Heat is produced for heating and hot-water supply by pyrolysis of domestic wastes and combustible refuse and materials in gas-generator autoclaves. Heat of exhaust gases from internal-combustion engine and electric heaters supplied with power from engine generator is used for heating and pyrolysis of combustible materials. Pyrolysis products in the form of combustible and flue gases are used as heat-carrying agents in heat-transfer apparatus of premises ventilation system and then condensed into liquid fuel in water boiler. Liquid fuel is used for engine running in working mode. Engine exhaust gases are passed through gas generators and then used as heat-carrying agents for heating radiators and further conveyed for heat accumulation in heat-storage materials, after that, to water heating boiled, whereupon they are exhausted into the atmosphere through detrimental-gas catalyst. Installation implementing proposed method is also described.

EFFECT: enhanced system efficiency and reduced consumption of expensive source energy carrier due to recovery of domestic wastes and combustible refuse thereby preventing pollution of environment.
