Integrated power self-supply system employing combined heat and power for centralized heating boiler house

Abstract

The invention relates to a concentrated heating boiler thermoelectric generating system, which comprises a heating boiler; a heating user; and a water pump that form the heating system, wherein it is characterized in that: the heating boiler is connected to the steam boiler via tube; the steam boiler via steam tube is connected to the inlet tube of turbine; the outlet tube of turbine is connectedto the heat exchanger; the condense water tank of heat exchanger via tube and water pump is connected to the oxygen remover; the oxygen remover via tube and water feeding pump is connected to the steam boiler; the output axle of turbine is connected to the generator; the output electricity of generator is connected to the electric appliance. The invention has high thermo-electric ratio, high heatutilization, small volume, and low cost.

Description

Technical field: [0001] The invention relates to a heating system, in particular to an intensive heating and power cogeneration power self-sufficiency system for a central heating boiler room. Background technique: [0002] At present, about 63% of the total heat of central heating in cities in my country is supplied by cogeneration of heat and power in thermal power plants, and about 35% is supplied by heating boiler rooms. With the development of excessive heating areas, public buildings account for 33.12% of the national central heating area, and civil buildings account for 59.76%. It can be seen that the central heating of central heating boiler rooms in winter still plays a very important role at present and in the future. The main components of the boiler room heating system, such as boiler auxiliary equipment and heat network circulation pump, are driven by electric motors. With the continuous increase of heat load, more and more equipment are required, and the power of...

Problems solved by technology

[0002] At present, about 63% of the total heat of central heating in cities in my country is supplied by cogeneration of heat and power in thermal power plants, and about 35% is supplied by heating boiler rooms. With the development of excessive heating areas, public buildings account for 33.12% of the national central heating area, and civil buildings account for 59.76%. It can be seen that the central heating of central heating boiler rooms in winter still plays a very important role at present and in the future. The main components of the boiler room heating system, such as boiler auxiliary equipment and heat network circulation pump, are driven by electric motors. With the continuous increase of heat load, more and more equipment are required, and the power of electric motors is also increasing. This makes the power consumption cost of heating enterprises account for a large proportion of production costs, and they have to pay expensive electricity fees to the power supply department every year, which seriously affects the economic benefits of enterprises and restricts their development.
