FIELD: heat-power engineering; heating systems; water heating systems, public services, agricultural sector and transport facilities.

SUBSTANCE: steam from electric steam generator is delivered to jet apparatus nozzle where it is mixed with cold liquid flow for forming two-phase flow at acceleration to supersonic velocity. At mixing chamber outlet, this two-phase flow is decelerated for forming shock wave and converting the flow into liquid flow after shock wave. Then, flow is divided and one part is directed to heat exchanger of vortex tube where it is heated and directed for replenishment of electric steam generator. Other part is directed to nozzle apparatus where it is accelerated to supersonic velocity for forming two-phase flow, after which it is decelerated for converting it into liquid flow saturated with micro-bubble component. Nozzle apparatus outlet is connected with swirler inlet where vortex flow is formed; from swirler, flow is directed to vortex tube where heat is released and flow is divided into hot and cold components. From vortex tube, flow is directed to heat exchanger for transfer of heat to second loop; cooled liquid flow is directed to ejector inlet.

EFFECT: enhanced efficiency of plant.

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.

FIELD: heat engineering, designed for rational heating of boiler house rooms for heat supply of industrial enterprises and residential districts.

SUBSTANCE: the method consists in bleeding of air outside the boiler house room. The boiler room with the id of a partition is divided into two isolated compartments. Mounted in the first compartment is the equipment giving off toxic solid and gaseous substances during operation thus contaminating the atmosphere (for example, boilers with burners), and installed in the second compartment is the equipment liberating heat during operation without liberation of harmful substances (heat exchangers, water heaters, etc.). The equipment of the second compartment liberates heat during operation that is accumulated under the building roof. This warm and clean air with the aid of ventilation plants is supplied through pipe-lines to the lower zone of both compartments located at the zero level. There is no need in use is made of already available resource.

EFFECT: reduced consumption of electric power for producing optimum temperature in the boiler house.

FIELD: heating equipment and cooling systems of rooms, applicable for maintenance of the temperature condition in dwelling houses and production areas both in winter and summer periods.

SUBSTANCE: the temperature condition in dwelling houses and production areas is maintained by circulation of air blown through by an air intake through a heat exchanger, a heated or cooled down working medium circulates inside it, and supplied through air conduits to the room to be heated/ cooled. The circulating air is saturated by a fine-dispersed liquid or by its vapors. Air supply is accomplished into the heating/ cooling panels with heat conducting walls forming a closed circulation system jointly with the air ducts, heat exchanger and air intake. The fine-dispersed liquid and condensed vapors are moved through the narrow ducts of the panels with the aid of the velocity head of the circulating air. The device for maintenance of the temperature condition in dwelling hoses and production areas is also described.

EFFECT: prevented or reduced forced air circulation in the room, enhanced share of the radiant component of heating or cooling, and prevented reduction of the relative air humidity in the room at its cooling.
