The invention discloses a cold-heat-steam-electricity quadruple combined supply technology for power generation of steam turbines for a factory. The cold-heat-gas-electricity quadruple combined supplytechnology comprises the following steps that (1) steam with the pressure of being 0.6MPa and the temperature of being 235 DEG C is provided by a back extraction unit to serve as inlet steam of an extraction condensing unit of a steam-driven air compressor; 2) the air compressor is driven to operate through an extraction condensing type steam-driven air compressor unit, the compressed air is generated, and the compressed air is supplied to the outside; (3) the pressure of steam extraction is 0.2MPa, and the steam is provided for a lithium bromide refrigerating unit to be used; and (4) in summer, the steam with the pressure of being 0.2MPa is extracted to be provided for the lithium bromide refrigerating unit, chilled water with the temperature of being 7 DEG C is generated to supply coldto the outside; and in winter, the steam with the pressure of being 0.2MPa exchanges heat with a plate heat exchanger, and water with the temperature of being 55 DEG C is heated to supply heat to theoutside. The technology solves the problems that due to the steam consumption is low, the generating capacity of a generator is reduced, and the contradiction between the generating capacity and thepower consumption of enterprises is large, an electric air conditioner is replaced, the auxiliary power is reduced, and energy can be made full use of.
Description
technical field [0001] The invention relates to the technical field of power generation, in particular to a four-cooling, heating, gas-power four-supply process for factory-used steam turbines for power generation. Background technique [0002] The steam turbine whose exhaust steam pressure is greater than atmospheric pressure is called a back pressure steam turbine. Each set of back pressure steam turbine unit is composed of multiple back pressure steam turbines. , Low pressure boiler, when the back pressure steam turbine is used to supply the original medium and low pressure steam turbine to replace the medium and low pressure boiler of the old power plant, it is also called the front type steam turbine, which can not only increase the power generation capacity of the original power plant, but also can Improve the thermal economy of the original power plant. [0003] The back pressure steam turbine unit generally determines the power generation of the unit according to th...
