Abstract

The invention belongs to the field of energy conservation of thermal power stations, particularly discloses an energy-saving heat supply system with a middle-positioned generator and a back-positioned back-pressure machine. The energy-saving heat supply system comprises a high and medium-pressure steam turbine cylinder and a low-pressure steam turbine cylinder which are connected via a single shaft. The energy-saving heat supply system is characterized in that the low-pressure steam turbine cylinder is connected with the generator, an exciter is coaxially arranged at the tail end of the generator and communicated with the back-pressure machine via a synchronous automatic gear shift clutch, a steam exhaust port of the high-and-medium-pressure steam turbine cylinder is communicated with the low-pressure steam turbine cylinder and the back-pressure machine via medium and low-pressure communication tubes, and a valve set A and a valve set B are respectively arranged on the communication tubes. The energy-saving heat supply system with the middle-positioned generator and the back-positioned back-pressure machine is simple in structure, convenient to use, reasonable in design and flexible in application, energy loss of the heat supply system can be effectively reduced, lost energy can be fully utilized, reliability of the whole system is improved, and investment is saved.

Description

(1) Technical field [0001] The invention belongs to the field of energy saving of thermal power plants, and in particular relates to a heat supply and energy saving system with the center of the power plant and the rear of the back pressure machine. (2) Background technology [0002] At present, in the transformation of domestic large and medium-sized thermal power generating units for cogeneration and heating, the method of extracting steam on the medium and low pressure connecting pipes is generally used for heating. In order to ensure the heating parameters, the parameters of the odor port at the first station of the heating network do not match the parameters of the working steam of the heating network heater, and there is a large throttling loss, especially for pure condensing reformed heating units, this problem is more prominent. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provid...
