Description
Technical field
The present invention relates to workshops to arrange field, refers in particular to a kind of Gas-steam Combined Cycle power plant main power house arragement construction.
Background technique
The relationships such as the main building arrangement scheme of Gas-steam Combined Cycle power plant and host model, crew qiting mode are close
It cuts.
Existing combined cycle generating unit includes Gas Turbine Generating Units and steam turbine generator group；Wherein combustion gas
Turbine generator group includes gas turbine, gas turbine powered generator and Gas Turbine Generating Units subsidiary engine equipment；Steam turbine hair
Motor group includes steam turbine, steam turbine generator and steam turbine generator group subsidiary engine equipment；Gas Turbine Generating Units
Also it is correspondingly arranged on afterheat boiler system；Steam turbine generator group is also correspondingly arranged on condenser system.
Due to gas turbine and the arrangement of steam turbine shafting, operating layer height, gas turbine inlet air mode, combustion gas
The difference of the relative position of turbine and steam turbine, there are more arrangement combinations modes for main building.
Typical high-order arrangement workshop is divided into three layers, i.e. zero meter of layer, middle layer and operating layer.Zero meter of layer and middle layer are main
The ancillary equipment of arrangement Gas Turbine Generating Units and steam turbine generator group, electrical and fire fighting device and each system pipe
Road.Operating layer is mainly used for arranging gas turbine, gas turbine powered generator, steam turbine, steam turbine generator and to these
The repair and maintenance of host equipment.
The advantages of high position arrangement, divides three-layer stereo to arrange for main building, and main building occupied area is small；Unit auxiliaries, electricity
Gas equipment and pipe arrangement space are abundant, and design difficulty is small；Each layer space for maintenance of main building and tour channel are spacious, are convenient for user
Daily Round Check；Main building operates on layer other than the main equipments such as Gas Turbine Generating Units, steam turbine generator group, without other
Ancillary equipment and pipeline, entire workshop is using joint large platform arrangement, the beautiful and tidy unification of pattern；Gas Turbine Generating Units,
The maintenance of steam turbine generator group can carry out on operating layer, and unit maintenance is very convenient, can satisfy multiple host simultaneously
The requirement of maintenance does not need that space for maintenance additionally is arranged；Workshop is arranged not by steam turbine discharge mode (i.e. condenser arrangement)
Limitation, high-order arrangement all can be used in steam discharge, axial exhaust and side steam discharge under steam turbine；Combustion turbine exhaustion road height compared with
Height, combustion turbine exhaustion from boiler horn mouth enter waste heat boiler after good dispersion degree be conducive to the heat exchange of waste heat boiler, while it is right
In the unit of setting denitrification apparatus, denitration efficiency can be improved；Gas Turbine Generating Units generator and steam turbine power generation machine are adopted
With the mode of lower part outlet, layer neat appearance is operated.
The disadvantage of high position arrangement is that main building height is higher, and workshop volume is big and cost is high, and the construction period is long；And
Since high position arrangement gas turbine inlet air generallys use lower part air inlet, need to reserve the arrangement space of gas handling system, this will lead to
Exhaust transition segment length between Gas Turbine Generating Units and waste heat boiler is longer, is vented crushing and low position is compared in radiation loss
It is larger.
Typical low position main building does not have middle layer and operating layer.Entire Gas Turbine Generating Units and steam turbine
Pipeline of generating set and its ancillary equipment, electrical equipment, fire-fighting equipment and each system etc. is all arranged in zero meter of workshop.
The advantages of low position is that main factory building height is low, and small in size, main building civil engineering and construction cost are low；Low position combustion
Gas-turbine generallys use top air inlet or side air inlet, and combustion turbine exhaustion is directly connected with waste heat boiler horn mouth, is vented segment length
Degree is shorter, is vented crushing and radiation loss is small.
The shortcomings that low position are as follows: main building takes up a large area；And due to host, subsidiary engine other all devices cloth all
It sets in zero meter of layer of main building, design difficulty is very big；Main building interior conduit and equipment arrangement are intensive, and tour channel is narrow, maintenance dimension
It protects very inconvenient；In addition, since without enough service areas, when unit maintenance, needs to move most of components in workshop
To outside workshop, it is also necessary to individually build the interim workshop for unit maintenance in workshop；Low position is limited to steam turbine steam discharge side
Formula, usual low position is suitable for the unit of steam turbine machine axial exhaust or side exhaust, for that can only use lower steam discharge
Steam turbine then cannot achieve low position；Between hollowing out under low position steam turbine condenser part needs are biggish, power plant is increased
Construction volume and cost；The position that low position combustion turbine exhaustion enters waste heat boiler is relatively low, into waste heat boiler after dispersion degree
Without the good of high-order arrangement, there is certain influence to the heat exchange of waste heat boiler, simultaneously for the unit of setting denitrification apparatus, denitration effect
Rate is good without high-order arrangement；The generator of low position must influence workshop beauty by the way of the outlet of top.
In recent years, it further saves construction investment and reduces project cost and have become the basic principle of power plant construction and become
The expectation of gesture and most of owners.Reasonable in order to reach the layout of the electric power factory equipment after building up and space utilization, pipeline connection is short
Prompt, neat, workshop inner facility characteristics of compact layout is appropriate, facilitates operation and maintenance to require, while meeting combined cycle generation again
