The invention relates to a power system and public utility and can be used in thermal power plants, as well as in the design of g (CHP) combined heat and power plants of cities and industrial hubs.

According to the main author. St. No. 935636 is known for the heat and power plant, containing the boiler to which the tour is connected with steam extraction pipelines on regenerative and network heaters connected to the feed and network water path, the condenser communicated by the feed and waste pipelines of the circulating water with the cooling system connected to the cold water main, which through the treatment facilities by the drinking water pipeline is connected to the consumer of drinking water and the consumer of hot and technical water, with the discharge pipeline of water is additionally connected to the consumer of industrial water and to the cold water main before the sewage treatment plant, 25 and the drinking water pipeline is connected to the consumer of hot water through an additionally installed water heater of the network water path l. thirty

The purpose of the invention is to increase the efficiency of heat use in variable modes while simultaneously expanding the functionality by supplying consumers with 35 cooled and hot drinking and process water.

This goal is achieved by the fact that the heat and power plant contains a boiler to which a turbine is connected with steam extraction pipelines for regenerative and networked heaters connected to the test and network water, a condenser connected to the feed and discharge pipe of the circulating water with a cooler. Connected to the cold water main, which, through the treatment facilities, drinking water pipeline connects with the consumer of drinking water and the consumer of hot and industrial water, with the waste water return pipe connected to the main water consumers and the cold water main facilities, and the drinking water pipeline is additionally installed1922

A water supply line path heater is connected to a hot water consumer, additionally equipped with heat pumps and hot and chilled water accumulators, the heat pump inlets being connected to industrial and / or potable water pipelines, and the outlets through the hot and cooled batteries. water - with appropriate consumers of drinking and process water.

The drawing shows a schematic diagram of a combined heat and power plant.

: The combined heat and power plant contains a boiler 1 connected to a turbine 2, and lastly to an electric generator 3 and in series with a condenser 4, a condensate pump 5, low pressure regenerative heaters 6 (HDPE), a deaerator 7 high pressure pump 8 and a regenerative heater 9 high pressure (LDPE) and boiler 1.

Pipelines 10–12 turbine outlets are connected respectively to LDPE 9, consumers 13 steam, peak boiler 14, PND bis network heaters 15 and t6. The condenser 4 through cooling water through the circulation pump 17 communicates with the cooler 18 and also through the waste pipe 19 of the circulating water, the valve 20 with the cooler, 18.

Discharge pipe 19 of circulating water through pipe 21 of heated water, heater 22, chemical cleaning 23, pump 24 is connected to condenser 4. Chemical cleaning 23 through charging pump 25 is connected by pipeline 26 to network supply path 27, on which network heaters 15 and 16 are installed, network pumps 28, peak water boilers 29, peak boiler 14 and water heaters 30. The cold water main 31 is connected to the cooler 18, and through the latch 32 to the sewage treatment plants 33, which through the pipeline 34 are drinking

the waters are connected through a water heater 30 to consumers of hot water 35 and through a heat pump 36, storage tanks 37 to consumers of hot water 38, through storage tank 39 to consumers of drinking water 40, and also through a heat pump 41, 3 D2 storage tank - with a consumption of 43 hot water. A heated water pipe 21 is connected by a black pipe 44, a heat pump 41, an accumulation tank 45 with consumers 46 of cold industrial water. In addition, a pipe 44 is connected to consumers 47 of heated water. The heat and power plant operates as follows. Steam from boiler 1 enters the turbine 2, from which it is partially taken for regeneration, steam supply to consumers and district heating. The exhaust steam enters the condensate 4. Water from the cold water main 31 is supplied to the cooler 18, and from there the circulation pump 17 to the condenser 4, where it is heated; exhaust steam. Then, the water through the discharge pipe 19 of the circulating water and then through the pipeline 21 of the heated water is directed through the heater 22, the chemical water treatment 23, the pump 24 to the condenser 4, and the make-up pump 25 to the network water path 27. In addition, through the pipeline 21, the heated water is directed to the treatment plant 33 and further through the pipeline 34 through the water heater 30 to the consumers of 35 hot water. From the water heater 30, the network water is supplied by the network pump 28 for subsequent heating to the network 24 heaters 15 and 16, the peak hot water boilers 29, the peak boiler 14 and again to the water heater 30. At the same time, the heated water through the pipeline 34 flows through the heat a potable water pump 36, storage tanks 37 and 39 to the corresponding consumers of hot 38 and 40 cooled potable water, and through a heat pump 41 of industrial water and an accumulator 42 to consumers of 43 hot water. The heated water from the pipeline 21 is also supplied through the pipeline 44 through the heat pump 41 of the industrial water, the storage tank 45 to the consumers 46 of the cooled technical water, and simultaneously through the pipeline 44 to the consumers 47 of the heated technical water. If it is necessary to regulate the temperature of the process and drinking water, cooler 18 is activated by supplying water from the main water 31 to it. The increase in the completeness of replacement of high-grade heat of withdrawal, which goes to the hot water supply using heat-generating installations for hot water supply, makes it possible to generate additional electricity and thereby cover the peak of power consumption. In addition, this effect is exacerbated by the use of storage tanks at consumers and the disconnection of heat pumps for the period of peak load.
