Description
Technical field
The present invention relates to the power generation system that a kind of fired power generating unit is coupled with air turbine.
Background technology
At present, the station service power consumption rate 300MW unit in the fuel-burning power plant of China self is about 5%～7%, 600MW unit and is about 4%～5%, 1000MW unit and is about 3%～4%. Therefore, often reduce the power supply for station of 1%, be equivalent to the thermal power output of the many offers 1% of China, so reducing station service power consumption rate will bring huge economic benefit to power plant. The technical scheme of now conventional reduction station service power consumption rate adopts small steam turbine to substitute high-power electric motor, such as adopts small steam turbine Direct driver service pump. But because the efficiency of small steam turbine is lower, so adopting the steam consumption that can increase full factory in this way, even reduce the overall power supply coal consumption of unit.
Summary of the invention
For the deficiency that prior art exists, it is desirable to provide the power generation system of a kind of lower station service power consumption rate.
The technical solution used in the present invention is:
The power generation system that boiler is coupled with air turbine, comprises thermal power generation unit, blower fan, pneumatic plant, high-temperature heat-exchanging, air preheater, boiler furnace, turbine and generator etc. Adjustment doors is installed at fans entrance place, and pneumatic plant has two gas inlets; Blower fan outlet is connected with the gas inlet of air preheater low-temperature zone with an entrance of pneumatic plant respectively by two pipelines; Adjustment doors is installed in another ingress of pneumatic plant; Controllable register installed by pipeline between blower fan and pneumatic plant. Blower outlet is connected with air preheater high temperature section gas inlet by pipeline, air preheater high temperature section air vout is connected with high-temperature heat-exchanging gas inlet by pipeline, high-temperature heat-exchanging air vout is connected with turbine inlet by pipeline, turbine outlet is connected with boiler furnace by pipeline, and high-temperature heat-exchanging is directly installed on the inside of boiler furnace. Blower fan, pneumatic plant and generator drive by air turbine.
The present invention utilizes air turbine system to be utilized by the high level heat that boiler combustion discharges, and the natural regenerative characteristics of system can also continue to utilize the discharge heat of internal combustion turbine, therefore has higher efficiency.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention 1 system schematic
Fig. 2 is the embodiment of the present invention 2 system schematic.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Description of reference numerals is as follows:
1 air turbine 2,3,5,6,14,16,17,21 air line
4 boiler furnace 7 high-temperature heat-exchangings
8 superheater and reheater 9,18,28,30 flues
10 condenser 11 steam turbine
12,25 generator 13 service pump
14 economizer 15 air preheater high temperature section
19,20,26,29 adjustment doors 22 blower fan
23 pneumatic plant 24 drive shafts
27 air preheater low-temperature zone
In embodiment 1 as shown in Figure 1, on the thermal power generation unit basis being made up of major equipments such as boiler furnace 4, steam turbine 11, generator 12, condenser 10, service pump 13, economizer 14, superheater and reheaters 8, be coupled air turbine power generation system, and the air turbine power generation system in Fig. 1 is made up of black thick line. Air enters in blower fan 22 by adjustment doors 26, is divided into two strands after blower fan 22 supercharging, and one is entered in air preheater low-temperature zone 27 by air line 17 and is heated, and then enters boiler furnace 4 through air line 5, as First air and the secondary air of boiler; Another strand of air enters pneumatic plant 23 through air line 21 and adjustment doors 19, then compressed in pneumatic plant 23, first high-pressure air after compression enters through air line 16 and carries out preheating in air preheater high temperature section 15, then enter high-temperature heat-exchanging 7 resume being arranged in boiler furnace 4 to be heated through air line 6, High Temperature High Pressure air after being heated enters expansion work in air turbine 1 through air line 2, air after acting enters in boiler furnace 4 through air line 3, in the process, adjustment doors 20 is in closing condition. Blower fan 22, pneumatic plant 22 and generator 25 drive by air turbine 1. If pneumatic plant 22 directly sucks air by adjustment doors 20 from air, so adjustment doors 19 is in closing condition.
In the embodiment 2 shown in Fig. 2, high-temperature heat-exchanging 7 is arranged on the outside of boiler furnace 4 as different from Example 1, flue 9 is now needed to utilize to be connected with boiler furnace 4 by the smoke inlet of high-temperature heat-exchanging 7 with 28, utilize flue 30 to be connected with boiler back end ductwork by the exhanst gas outlet of high-temperature heat-exchanging 7 simultaneously, flue 30 is provided with adjustment doors 29 above, is convenient to regulate the flue gas flow flowed through in high-temperature heat-exchanging 7.
Boiler smoke eventually passes flue 18 and drains.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw the product of other various form under the enlightenment of the present invention. Though but in its shape or structure, do any change, every technical scheme identical or close with the present invention, all within its protection domain.
