Main power house for side-position arranged turbine generator

Abstract

The invention discloses a main power house for a side-position arranged turbine generator, which at least comprises a boiler house, a bunker room, a deoxidizing room and at least one turbine generator machine room. One of the turbine generator machine rooms is adjacent to one side of the boiler house. With the adoption of the main power house for the side-position arranged turbine generator, the length of the high-temperature pipe is greatly shortened, the engineering investment is obviously reduced and the normal operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power generation, in particular to a design of a main building of a steam turbine power plant arranged sideways. Background technique [0002] The common composition scheme of the main building of the turbogenerator in the prior art is as follows: Figure 1a , Figure 1b , Figure 2a and Figure 2b shown. Figure 1a and Figure 1b It is the most common single-shaft turbogenerator main building. Such as Figure 1a and Figure 1b As shown, in a conventional thermal power plant, the main building usually consists of 4 rows of turbine room, deaeration room, coal bunker room, and boiler room, and the turbine generator is arranged in the turbine room in front of the furnace. in particular, Figure 1a and Figure 1b In , the single-shaft turbogenerator is arranged in front of the furnace. Figure 2a and Figure 2b It is a common twin-shaft turbo-generator main workshop, which consists of 4 rows of turbine...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the side-positioned steam turbine-generator main plant building of the present invention has a large distance between the steam-turbine-generator and the boiler for the conventional front-position layout, which results in a long distance between the high-temperature interface between the steam turbine and the boiler, and a relatively small pipe system. Long, high investment, large flow resistance and low efficiency, all or part of the turbogenerator shafting is arranged on the left or right side of the boiler, thereby greatly shortening the length of the high-temperature piping system, significantly reducing the engineering investment, and reducing the system flow resistance, improve normal operating efficiency, and thus have a better return on investment
