As the utility model optimized technical scheme, the effect of oxygen flow control valve is the flow that control enters the oxygen of firing chamber; Oxygen sensor can be responded to the oxygen content in the gas after the burning of discharging the firing chamber, be provided with a lower limit and a CLV ceiling limit value in it, be lower than this lower limit as oxygen content in the gas of discharging, then oxygen sensor sends a pilot signal to the oxygen flow control valve, the oxygen flow that makes its control enter the firing chamber increases, otherwise, content as oxygen in the gas of discharging is higher than this CLV ceiling limit value, then oxygen sensor sends another pilot signal to the oxygen flow control valve, and the oxygen flow that makes its control enter the firing chamber reduces; Temperature inductor can be responded to the temperature of air outlet, firing chamber, also be provided with a lower limit and a CLV ceiling limit value in it, be lower than this lower limit as place, air outlet, firing chamber temperature, then temperature inductor sends a pilot signal to the oxygen flow control valve, the oxygen flow that makes its control enter the firing chamber increases, otherwise the temperature of locating as the air outlet, firing chamber is higher than this CLV ceiling limit value, then temperature transducer sends another pilot signal to the oxygen flow control valve, and the oxygen flow that makes its control enter the firing chamber reduces.
Compared with prior art, gas turbine of the present utility model need not be provided with gas compressor, and is simple in structure, reduce cost; Adopt the combustion improver that isolated pure oxygen acts as a fuel and burns in the air separation station, make the fuel combustion in the firing chamber more abundant, discharge more heat, generate the combustion gas of higher temperature, effectively improved the efficient of gas turbine.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a modular structure schematic representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model can realize that the gas turbine engine systems of pure oxygen clean combustion comprises an air separation station and a gas turbine, pure oxygen can be isolated in the air separation station from liquid air, be provided with a firing chamber and a combustion gas turbine that communicates with the firing chamber in the gas turbine, the firing chamber is provided with an oxygen suction port and a fuel inlet, and a fuel reserve device is communicated to this fuel inlet; Between the oxygen suction port of the oxygen outlet at air separation station and firing chamber by pipeline be linked in sequence a reduction valve, a solenoid valve, a pressure maintaining valve, an one-way valve and an oxygen flow control valve, the place, air outlet of firing chamber is provided with an oxygen sensor and a temperature transducer, and this temperature transducer all is connected with the oxygen flow control valve with oxygen sensor.The effect of reduction valve is the high pressure oxygen pressure that the air separation station emits to be reduced to one be higher than atmospheric value, and this reduction valve is adjustable, promptly by regulating the parameter of reduction valve, the hyperbaric oxygen gas by reduction valve can be adjusted to the Oxygen Flow of the pressure that needs; Solenoid valve is a system switching, and whether may command oxygen passes through; The effect of pressure maintaining valve is with through the post-decompression pressure instability of reduction valve, inconsistent Oxygen Flow voltage stabilizing, makes it to become the stable and consistent Oxygen Flow of pressure; The effect of one-way valve is that the control Oxygen Flow can only be to firing chamber oxygen suction port direction one-way flow; The effect of oxygen flow control valve is the flow that control enters the oxygen of firing chamber; Oxygen sensor can be responded to the oxygen content in the gas after the burning of discharging the firing chamber, be provided with a lower limit and a CLV ceiling limit value in it, be lower than this lower limit as oxygen content in the gas of discharging, then oxygen sensor sends a pilot signal to the oxygen flow control valve, the oxygen flow that makes its control enter the firing chamber increases, otherwise, content as oxygen in the gas of discharging is higher than this CLV ceiling limit value, then oxygen sensor sends another pilot signal to the oxygen flow control valve, and the oxygen flow that makes its control enter the firing chamber reduces; Temperature inductor can be responded to the temperature of air outlet, firing chamber, also be provided with a lower limit and a CLV ceiling limit value in it, be lower than this lower limit as place, air outlet, firing chamber temperature, then temperature inductor sends a pilot signal to the oxygen flow control valve, the oxygen flow that makes its control enter the firing chamber increases, otherwise the temperature of locating as the air outlet, firing chamber is higher than this CLV ceiling limit value, then temperature transducer sends another pilot signal to the oxygen flow control valve, and the oxygen flow that makes its control enter the firing chamber reduces.
When gas turbine engine systems of the present utility model is worked, open solenoid valve, the isolated pure oxygen in air separation station is passed through solenoid valve after reduction valve reduces pressure, again through the pressure maintaining valve voltage stabilizing, through the one-way valve control flows to, combine its flow of control with the oxygen flow control valve through temperature transducer and oxygen sensor again, after gas pipeline sprays into the oxygen suction port of firing chamber, fuel in the fuel reserve device is sprayed into by the fuel inlet of firing chamber simultaneously, fuel and pure oxygen react, fuel combustion, become high-temperature fuel gas, flow into expansion working in the described combustion gas turbine immediately, promotion turbo wheel band compressor impeller and is rotated together.
Because the high pure oxygen of the isolated pressure in air separation station just reduces pressure through reduction valve, the oxygen pressure that enters gas-turbine combustion chamber still has very big pressure, so gas turbine of the present utility model need not to be provided with gas compressor, saves cost.
