Abstract

The invention discloses a 200 MW ultrahigh pressure back-pressure steam turbine, and relates to a 200 MW turbine. The aim is to meet the winter heat supply need. One end of a back-pressure polished shaft rotor is connected with a high and medium pressure rotor through an adjusting end coupler bolt, and the other end of the back-pressure polished shaft heat supply rotor is connected with a power generator rotor through an electric end coupler bolt; and an intermediate pressure cylinder steam exhaust port is connected with a heat network heater through a heating steam extraction pipeline and isfurther connected with the steam inlet end of a cooling steam system through a cooling steam pipeline, and the steam outlet end of the cooling steam system is connected with a steam inlet of a low pressure cylinder. The turbine can meet the winter heat supply need.

Description

technical field [0001] The invention relates to a 200MW steam turbine. Background technique [0002] At present, due to the increase of the heating area in winter, it is necessary to increase the heating capacity and require a larger steam extraction volume. Simply relying on drilling steam extraction on a steam extraction pipe of the steam turbine can no longer meet the demand. Contents of the invention [0003] The object of the present invention is to provide a 200MW ultra-high pressure back pressure steam turbine to meet the heating demand in winter. [0004] A 200MW ultra-high pressure back-pressure steam turbine according to the present invention comprises a back-pressure optical axis rotor 1, an end-adjusting coupling bolt 2, an electric-end coupling bolt 3, a heating extraction steam pipeline 4, and a cooling steam pipeline 5 and cooling steam system; [0005] One end of the back pressure optical axis rotor 1 is connected to the high and medium pressure rotor thr...
