The gas turbine of the present embodiment, including compressor, combustion chamber, the first output turbine and the second output turbine；Wherein,
The compressor and the combustion chamber, the first output turbine and the second output turbine respectively with combustion chamber, and
First output turbine and compressor are coaxial, and the second output turbine and the first output turbine be not coaxial.The compressor is from outer
Boundary suck air and in it air compression supercharging and will be in compressed gas force feed to the combustion chamber；The combustion chamber is by institute
The fuel stated compressed air and be injected into is mixed and burned generation high-pressure gas；A part for the high-pressure gas is described for driving
First output turbine, another part is for driving the second output turbine.Due to only having the first output turbine to be and compressor
Coaxial, the second output turbine and compressor be not coaxial, in this way, the position that the second output turbine is arranged is relatively free, no longer by
To stringent limitation, while but also relatively free by the setting of the equipment of the second turbo-driven outside of output, i.e. combustion gas wheel
The setting of the equipment of the outside of machine driving is relatively free, can be formed according to the equipment of gas turbine and the outside of its driving whole
The needs of the function and structure of a system are configured.
When gas turbine starts, it is necessary first to which exterior power, usually starter drive compressor, until first
When the mechanical work that output turbine is sent out is more than the mechanical work of compressor consumption, extraneous starter is threaded off, and gas turbine could itself
It works independently.Therefore, after the gas turbine independent operating, the mechanical work that driving the first output turbine is sent out is more than described
The mechanical work of compressor consumption.This is the requirement that gas turbine itself can work independently.
Second output turbine of the equipment in order to realize the multiple outsides of gas turbine drives, gas turbine can be multiple.
The quantity of second output turbine determines the quantity of the equipment for the outside that gas turbine can drive.It can be according to gas turbine need
The quantity of the equipment for the outside to be driven determines the quantity of the second output turbine.
Specifically, in order to realize the connection of the first output turbine and combustion chamber, as shown in Figure 1, gas turbine further includes
One gas pipeline 410, the first output turbine 310 are connect with the gas outlet of combustion chamber 200 by the first gas pipeline 410.
In this way, being achieved that the first output turbine and combustion chamber by the first gas pipeline.
Specifically, in order to realize the connection of the second output turbine and combustion chamber, as shown in Figure 1, gas turbine also needs to wrap
The second gas pipeline 420 is included, the second output turbine and the gas outlet of the combustion chamber pass through second Gas Pipe
Road 420 connects.In this way, being achieved that the second output turbine and combustion chamber by the second gas pipeline.
About the effect of the first output turbine, it is only used for driving compressor.Thus, it is desirable in gas turbine independent operating
Afterwards, the mechanical work that the first output turbine is sent out is driven to be more than the mechanical work of the compressor.
About the effect of the second output turbine, for driving external equipment.Each second output turbine drives one
External equipment.Drive different external equipments, the demand for the work(that the second output turbine is sent out that may be different, it is therefore desirable to
According to the external equipment that the second output turbine is driven, the height of corresponding driving the second output turbine is distributed for the second output turbine
The amount of compression ignition gas.In order to realize the distribution and control of high-pressure gas, as shown in Figure 1, all second is exported its in turbine
In one be set as adjust with second output turbine 321, other for work with second export turbine 322；
The second output whirlpool of the work, 322 are provided with control valve 510 with second gas pipeline junction, described
Control valve 510 is used to control the amount for the high-pressure gas for driving the work with the second output turbine 322；
Described adjust is provided with overflow valve 520 with the second output turbine 321 with second gas pipeline junction, described
Overflow valve 520 is used to adjust the amount by the high-pressure gas of the overflow valve and keeps the institute in second gas pipeline
The pressure of high-pressure gas is stated within preset range.
In this way, according to each work amount of the high-temperature fuel gas needed for the second turbo-driven external equipment of output, pass through
Adjust the amount of each work of the control valve control driving high-pressure gas of the second output turbine.In order to ensure the second gas pipeline
The pressure of interior high-pressure gas within a preset range, needs extra high-pressure gas the discharge area out of second gas pipeline, because
This, is provided with overflow valve with second gas pipeline junction with the second output turbine adjusting, passes through the overflow valve tune
Section keeps the pressure of the high-pressure gas in second gas pipeline by the amount of the high-pressure gas of the overflow valve
Within preset range.It adjusts and can be used for driving the steady of the amount of high-temperature fuel gas needed for external equipment with the second output turbine
The not high equipment of qualitative requirement, or be directly used in driving and be only used for consuming the extra ancillary equipment for stating high-pressure gas.It is existing
In technology, in order to control the speed that driving exports the high-pressure gas of turbine, need that retarder is arranged, the presence of retarder causes to fire
The utilization rate of the energy of gas-turbine greatly reduces.In this way, it is no longer necessary to which retarder simplifies the second output of each work of driving
The control difficulty of the amount of the high-pressure gas of turbine, simplifies control method, improves the utilization rate of the energy of gas turbine.
In order to realize that the high-pressure gas of combustion chamber respectively enters the first gas pipeline and the second gas pipeline, need burning
Flow divider is arranged in the gas outlet of room, and the flow divider is used to a part for the high-pressure gas being further separated into the first combustion gas
Another part is further separated into the second gas pipeline by pipeline.By the way that flow divider is arranged, the high-pressure gas of combustion chamber is shunted into difference
Into the first gas pipeline and the second gas pipeline.
In order to realize that the control to control valve and flow divider, gas turbine further include control unit, described control unit is used
In the control control valve and the flow divider.
As a preferred mode, the part of the high-pressure gas of the first output turbine is driven to be no more than all
The 1/3 of the high-pressure gas of the combustion chamber.In this way, it is ensured that the high-pressure gas of most of combustion chamber is for driving outside
Equipment.
As a preferred mode, the compressor is axial-flow compressor.
Obviously, those skilled in the art the utility model embodiment can be carried out various modification and variations without departing from
The spirit and scope of the utility model.In this way, if these modifications and variations of the present invention belong to the utility model right
It is required that and its within the scope of equivalent technologies, then the utility model is also intended to include these modifications and variations.
