Description
Technical field
The utility model is related to gas combustion-gas vapor combined cycle factory technical field, more particularly to a kind of combustion and steam joint
Cycle power plant main building arrangement structure.
Background technology
For gas combustion-gas vapor combined cycle factory, main building is one of most crucial building, most of host device
With main therrmodynamic system process pipelines, the equal centralized arrangement of cable in main building.The conjunction of main building and its process equipment arrangement
Rationality, affect building volume, process pipelines cable kilometer, construction organization order, power plant construction cycle length and
The operation safety and convenience of electric power factory equipment.
Combined cycle power plant's main building arrangement structure includes combined cycle generating unit, often covers combined cycle generating unit
It is divided into gas turbine generator group, vapor wheel generating set and the part of waste heat boiler three.Gas turbine generator group include gas turbine,
Gas turbine generator and its auxiliary equipment.Vapor wheel generating set includes steam turbine, steam turbine generator and its auxiliary equipment.
Waste heat boiler includes boiler body and its auxiliary equipment, and its arrangement form depends primarily on the exhaust mode of gas turbine, with combustion
Relation between gas-turbine is relatively fixed.
In gas combustion-gas vapor combined cycle factory, most important equipment is exactly gas turbine, and its structure type decides master
The arrangement general layout of factory building.Gas turbine can use side air inlet, three kinds of frame modes of upper air and lower air inlet.When gas turbine is used
During the intake method of side, the air induction system of side air inlet can only be mounted in gas turbine side, and not allow mirror-image arrangement.If hair
When there are many set Combined Cycle Units in power plant, in order to avoid adjacent Combined Cycle Unit and its factory building are entered to the air of gas turbine
The air of gas system produces disturbance destruction, often cover Combined Cycle Unit position must assure that certain safe operation away from
From, therefore main building is typically using the plant layout structure that often set Combined Cycle Unit is independently arranged.When under gas turbine use
During intake method, the air induction system of lower air inlet is arranged in below gas turbine, and air inlet is towards waste heat boiler, in order to ensure
Air inlet amount and relatively low flow passage resistance force of waterproof, gas turbine are necessary for high-order operating layer arrangement, the steam turbine with high position arrangement
It can be arranged with layer.When gas turbine uses upper air mode, taken up too much space by the air induction system of upper air and
Air inlet is needed in outdoor, therefore gas turbine is low position, can be arranged with the steam turbine of high-order or low level with layer.
It is general both at home and abroad that upper air low position is used to gas turbine in order to reduce main building cost.Moreover, combustion gas is steamed
Vapour combined cycle power plant main building arrangement structure is diversified, is mainly reflected in gas turbine generator group and vapor wheel generates electricity
Relation between unit.For example, in the technical scheme having, a set of steam turbine and a set of combustion turbine combined formation are single
Combined Cycle Unit, and form self plant layout structure；In the technical scheme having, cover united steam turbine and many more
Cover united gas turbine and form many set Combined Cycle Units, and form united main building arrangement structure respectively；In the skill having
In art scheme, all combined steamed gas turbines together, form joint main building arrangement structure.

The equipment in-line arrangement of Combined Cycle Unit is covered in same main building, and vapor wheel generating set is arranged in gas turbine generator
The left side or right side of group；Joint main building sets three layers of inspection platform altogether, respectively zero meter layer, intermediate layer and operating layer, fortune
Turn layer platform arrangement steam turbine generator group and gas turbine generator group, the auxiliary equipment belonging to them is corresponded under it respectively
Each layer inspection platform arrangement in side；Often set Combined Cycle Unit sets a maintenance driving, and the institute of unit is often covered to overhaul lifting
There is major-minor machine equipment；Turbine generator and gas turbine powered generator are taken out rotor and realized by same travelling crane inspection lifting；Often
Combined Cycle Unit setting one is covered across maintenance across its access path A before main building is discharged into out；Main building roof absolute altitude is in 30m
More than, main building and driving span are about 45m.The technical scheme has following several shortcomings：Host device is high-order arrangement, if
The civil engineering costs such as standby basis, pile foundation are higher；Main building takes out dress to consider that generator amature is overhauled indoors, thus main building and
Span of driving a vehicle is very huge, about 45m, so factory building volume is larger, while civil engineering cost is high, driving cost is also higher；It is main
The total floor space of factory building is larger, it is desirable to which power plant place is well-to-do, and expropriation of land cost is higher；For the vapor wheel of low position axle steam discharge
Machine, is not suitable for this combustion turbine combined arrangement main building scheme with air inlet under high-order arrangement；The large scale equipments such as condenser
It because being arranged in factory building center, it is impossible to assemble and promoted comprehensively in factory building outside factory, can only assemble, install in factory building narrow space
Construction period is longer.
