The invention relates to a high back pressure heat supply system of an indirect air cooling steam turbine. The high back pressure heat supply system comprises a condenser, a heat network return watermain pipe and a heat network return-water-to-condenser water inlet pipeline, wherein the heat network return water main pipe is connected with the heat network return-water-to-condenser water inlet pipeline, the heat network return-water-to-condenser water inlet pipeline is divided into a first water inlet pipeline and a second water inlet pipeline, and the first water inlet pipeline communicateswith a condenser through the inlet on the side A of the condenser and is connected with a first water outlet pipeline through the outlet on the side A of the condenser; the second water inlet pipelinecommunicates with the condenser through the inlet on the side B of the condenser and is connected with a second water outlet pipeline through the outlet on the side B of the condenser; and the firstwater outlet pipeline and the second water outlet pipeline are combined and then are connected with the heat network return water main pipe, and the first water outlet pipeline and the second water outlet pipeline are provided with on-line monitoring devices. According to the system, the hot network return water is connected into the condenser, and the waste heat discharged from the waste steam ofthe condenser is recycled to carry out resident heating, so that the cold source loss is reduced, the heat supply capacity is improved, and the heat efficiency of an indirect air cooling heat supplypower station is improved.
Description
technical field [0001] The present application relates to the technical field of heat supply, in particular to an indirect air-cooled steam turbine high back pressure heat supply system. Background technique [0002] With the lack of energy and the increasing requirements for energy conservation and emission reduction, the comprehensive utilization technology of energy is constantly improving. As a large energy consumer, the energy saving of thermal power plants has always been the focus of industrial energy saving. With the rising coal price, energy saving and emission reduction is also an important means for the power plant itself to save operating costs and improve economic benefits. [0003] At present, the heating method of each heating power station adopts steam extraction in the middle of the steam turbine to heat the circulating water of the heating network, and then sends it to the heat user for heating and heating of residents. The steam completed by the steam tur...
