Abstract
The super expansion turbine unit belongs to gas turbine installation, installs the heat energy of the pressure of discharge a little more than the high-temperature gas of ambient atmosphere pressure in order to utilize gas turbine or other.High-temperature gas is expanded to the pressure far below ambient atmosphere pressure in the turbine of unit, cooled by other medium through heat exchanger then, enters atmosphere or other devices by compressor compresses.Because expansion work is greater than the required merit of compression, the external output work of unit.
Description
The invention belongs to gas turbine installation.
The widely-used gas turbine in countries in the world is the power source of aircraft, generator set, locomotive, boats and ships, automobile at present.The gas temperature that he discharges has so just lost a sizable part by the heat energy that obtains in the fuel far above the ambient air temperature.In order to improve the Economy of gas turbine, people have adopted several different methods to utilize heat energy in the gas that its discharges, wherein have:
Regenerator, the heat of absorb discharging gas with regenerator come before the heating flame chamber gas through overcompression, to reduce the consumption of fuel;
Gas turbine-steam turbine combined cycle, the high-temperature gas heating water generates water vapor with gas turbine is discharged promotes the steam turbine output work;
Steam-recycling formula gas turbine, the high-temperature gas of discharging with gas turbine adds hot water, produces water vapor, injects the external output work of turbine of gas turbine.
The generality introduction of these methods visible " gas turbine " (department of power engineering gas turbine teaching and research room of Tsing-Hua University compiles, hydraulic and electric engineering publishing house version in 1978) and " development and the structural feature thereof of aviation remodeling steam-recycling formula combustion machine " (Air International magazine the 9th phase of nineteen ninety).
The present invention proposes to use the super expansion turbine unit to utilize the external output work of heat energy that gas turbine is discharged and the high-temperature gas (except the water vapor) that other devices are discharged.
Super expansion turbine unit such as accompanying drawing are made up of with pipeline turbine, heat exchanger, compressor and connection, and other component such as valve wherein can be housed.
The turbine outlet pressure of general gas turbine is a little more than barometric pressure, and turbine outlet pressure of the present invention is far below barometric pressure.So called after super expansion turbine unit of the present invention.Turbine of the present invention can be the part of front end gas turbine turbine, also can be an independent turbine.
Working procedure of the present invention is as follows:
Enter the turbine 1 of super expansion turbine unit by the high-temperature gas of front end gas turbine or other device discharges, expand into pressure while output work therein far below ambient atmosphere pressure, gas enters the heat exchanger 2 that cooling medium can be liquid or gas then, the cooling that is cooled enters atmosphere or other devices by compressor 3 compressions then.Owing to the compression work of gas expansion work greater than absorption, the externally clean output work of this unit.
This unit can in position be provided with valve so that control.
Advantage of the present invention:
1. can utilize the heat energy of the pressure of front end gas turbine or other device discharges a little more than the high-temperature gas of ambient atmosphere pressure;
2. the super expansion turbine unit can be used as a cover isolated system and is connected in front end gas turbine and other and discharges after the device of High Temperature Gas, and external output work does not influence original gas turbine or other devices separately;
3. the turbine of this unit design that can be integrated with the turbine of front end gas turbine improves design flexibility;
4. the back temperature descends because high-temperature gas expands in turbine, and heat exchanger can be less than the heat exchanger in backheat circulation and the gas turbine-steam turbine combined cycle, and compressor is also less, can reduce cost;
5. this unit still might be raised the efficiency with the method for backheat or steam-recycling.
Best implementation of the present invention is that turbine is coaxial with compressor, adopts liquid cooling heat exchanger and rotary-vane compressor, goes up output work from the axle that compressor extends out.
Claims (5)
1, a kind of super expansion turbine unit that utilizes pressure a little more than the external output work of heat energy of atmospheric high-temperature gas.It is made up of turbine, heat exchanger, compressor and some other component.It is characterized in that high-temperature gas expand into the pressure far below ambient atmosphere pressure in turbine, simultaneously external output work.This gas arrives lower temperature through cools down then, enters atmosphere or other devices by compressor compresses.Because the expansion output work is greater than the required merit of compression, this unit is output work externally;
2, super expansion turbine unit as claimed in claim 1, its turbine can join together with the turbine of front end gas turbine and manufacture and design;
3, heat exchanger according to claim 1, its cooling medium can be liquid or gas;
4, super expansion turbine unit as claimed in claim 1 can be controlled operating mode by the valve on the pipeline before or after turbine, heat exchanger, the import and export of cools down medium, the compressor;
5, compressor as claimed in claim 1 can be rotary-vane compressor or other compressors.
