Main power house allocation structure of high-capacity thermal power station

Abstract

The invention relates to a main power house allocation structure of a high-capacity thermal power station. The main power house allocation structure of the high-capacity thermal power station comprises a steam engine room, a deaerator room, a bunker room and a boiler room. The ground level of the boiler room is higher than that of the bunker room, the ground level of the bunker room is higher than that of the steam engine room and the deaerator room, and the ground level of the steam engine room is the same as that of the deaerator room. The main power house allocation structure has the beneficial effects that 1, under the premise of remaining the schemes of the whole station ground level layout and relative technology systems unchanged, the main power house structure adopts negative excavation layout to decrease the layout ground level of a condenser so as to decrease the height difference between the condenser and a water taking port, so that the limited technical standard requirements for lifting of relative technology equipment are met; 2, by adopting the stepped negative excavation layout on the main power house structure, under the premise of combining the technology layout, the height difference between the condenser and the water taking port can be decreased maximally; and 3, the main power house allocation structure has high adaptability and practicability.

Description

technical field [0001] The invention relates to a layout scheme of step-type negative excavation for the structure of the main building of a large-capacity thermal power plant. Background technique [0002] The design floor elevation of the thermal power plant is mainly determined based on factors such as the topography and geological characteristics of the site area, the land policy of the area where the site is located and related environmental protection policies, the earthwork function of the plant site leveling, and the head of the circulating water pump of the DC water supply system. In view of the diversity of site conditions and engineering geology, the increasing standards of land and environmental protection policies, and the limited requirements of earthworks for site leveling in the plant area, the site elevation determined by the general layout cannot always meet the limited requirements for the lift of circulating water pumps . When the main factory building i...

Problems solved by technology

However, the adoption of the recirculation water supply system scheme is an adjustment of the design concept of the overall process system, which increases the complexity of the process system and requires additional equipment, facilities and construction sites, thereby increasing the construction investment of the power plant; at the same time, after the power plant is put into operation , will also increase the production and operation cost of the power plant

Obviously, this solution is not an ideal solution
