Embodiment 1

[0073] image 3 It is a structural diagram of the front steam turbine generator room with side coal bunkers combined with high-level arrangement in Embodiment 1 of the present invention.

[0074] and figure 2 Compared with the main workshop of the steam turbine generator shown, the present invention arranges the front machine room of a single unit above the side coal bunker through the side coal bunker frame.

[0075] The structure of the front steam turbine generator room with side coal bunker combined with high position arrangement of the present invention includes: 2 boilers, a side coal bunker room located in the middle of the boiler, 2 oxygen removal rooms, the first steam turbine generator, and the second steam turbine generator machine and denitrification steel frame; wherein, a deoxygenation room is set on the side adjacent to the proximal end of the side coal bunker, a turbine room is set on the side adjacent to the deoxygenation room, and a second steam room is set...

Embodiment 2

[0082] Figure 4 It is a structural diagram of the front steam turbine generator room with side coal bunkers combined with high-level arrangement in Embodiment 2 of the present invention.

[0083] Embodiment 2 of the present invention is similar to Embodiment 1, with the difference that: the front-end machine rooms of the two first steam turbine generators are combined and arranged above the side coal bunker located in the middle of the two boilers. The volume of the front-end machine room of the two units is 72000m 3 .

[0084] The high-positioned pre-turbine generator room in this embodiment 2 can reduce the site of the main steam pipeline by 50%-60%, and the relative length of the main steam pipeline can reach 3 / 10, and the absolute length is ≤40m. The length of the connecting piping system can be shortened to 60m, the cost of the main steam pipeline can be saved by 45%, the overall cost can be reduced by 18%, and the pipeline efficiency can be increased by more than 58%....

Abstract

The invention provides a prepositioned turbogenerator room combined with a side coal cabin and arranged on a high position. The room comprises a boiler, a side coal cabin chamber, an oxygen removing chamber, a first turbogenerator, a second turbogenerator and a denitration steel frame, wherein the oxygen removing chamber is arranged on one side adjacent to the near end of the side coal cabin chamber; a steam turbine room is arranged on one adjacent side of the oxygen removing chamber; the second turbogenerator is arranged in the steam turbine room; the second turbogenerator is provided with a high-pressure cylinder, a middle-pressure cylinder, a low-pressure cylinder, a low-pressure heater and an oxygen remover, a steam condenser, a condensation water pump and a first generator; a side coal cabin framework is arranged on the side coal cabin chamber; a prepositioned machine room is arranged on the upper part of the side coal cabin framework; the lower part of the side coal cabin framework is connected with the side coal cabin chamber; the first turbogenerator is arranged in the prepositioned machine room. By the aid of the prepositioned turbogenerator room, the occupying area of a prepositioned set is reduced; high-temperature and high-pressure pipelines are saved; the investment of a high-temperature pipe system can be greatly reduced and the normal operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of power plant structure, in particular to a front steam turbine generator room combined with a side coal bunker and arranged at a high position. Background technique [0002] In a conventional thermal power plant, due to the large volume and heavy equipment of the turbogenerator, it is usually arranged on a base raised from the ground, and the cost of the civil structure is relatively low. However, since the boiler is relatively high, and the main piping system interfaces such as boiler main steam and reheating are located on the upper part of the boiler, the length of the main steam, reheating, etc. The cost is high; and the piping system is long, which will lead to a corresponding increase in flow resistance and reduce the economy of the normal operation of the unit. [0003] For the transformation of sub-temporary units into ultra-supercritical double reheat units, the layout of the above-mentioned front-end mach...
