Abstract

The invention relates to a turbine, in particular to a 150MW ultrahigh pressure steam extraction and condensing type turbine, and aims to solve the problems that steam is extracted from a steam extraction pipeline connection pipe of a 150MW turbine unit and the extraction flow of steam cannot be controlled so that energy loss is caused, and the turbine unit efficiency is reduced. The turbine comprises a front bearing box, an ultrahigh pressure and high-intermediate pressure combined cylinder, a middle bearing box, an ultrahigh pressure and low pressure cylinder, a rear bearing box, a rotary baffle, a rotary mechanism and a power mechanism; the ultrahigh pressure and high-intermediate pressure combined cylinder is connected between the front bearing box and the middle bearing box, and the ultrahigh pressure and low pressure cylinder is connected between the middle bearing box and the rear bearing box; the rotary baffle is mounted in the ultrahigh pressure and high-intermediate pressure combined cylinder and comprises a plate body outer ring, a plate body inner ring, a rotary ring, a cover ring, an elastic sealing ring, a connection convex handle and a stationary blade; the rotary ring is arranged between the cover ring and the plate body outer ring, and the cover ring is connected with the plate body outer ring. The 150MW ultrahigh pressure steam extraction and condensing type turbine is used for heating power generation of combined heat and power generation.

Description

technical field [0001] The invention relates to a steam turbine, in particular to a 150MW ultra-high pressure industrial steam extraction and condensing steam turbine. Background technique [0002] The parameters of the domestic industrial steam extraction 150MW steam turbine unit currently in operation are mainly to take over the extraction steam from the steam extraction pipeline, and the extraction steam volume cannot be controlled, resulting in energy loss and reducing the working efficiency of the unit. Contents of the invention [0003] The present invention aims to solve the problem that the existing 150MW steam turbine unit takes over steam extraction from the steam extraction pipeline, cannot control the steam extraction volume, causes energy loss, and reduces the working efficiency of the unit, and further provides a 150MW ultra-high pressure steam extraction and condensing steam turbine. [0004] The technical scheme adopted by the present invention to solve the...
