Formula.The gas-turbine of closed cycle gas turbine engine device is had been reported that for commercial electricity production, and Stirling engine has many-sided technical problem
So far fail to solve, do not there is practical commercial value.Using external heat mode, can suitable for multiple fuel particularly inferior fuel,
Nuclear energy can also be utilized, so its great advantage is any external heat energy to be converted to mechanical work.
The gas-turbine of closed cycle gas turbine engine device, by being constituted including compressor, gas-turbine, heater, cooler etc., calms the anger
Machine and gas-turbine power connector, often using helium as working medium.During work, helium is compressed in compressor after boosting, delivers to heater
Heated under the conditions of level pressure from outside, the temperature of helium is reached required high temperature.Then, high temperature helium enters in gas-turbine
Row adiabatic expansion, promotes impeller output shaft work.It is finally that the low pressure helium feeding cooler level pressure heat release after expansion working is complete
Into whole closed loop thermodynamic cycle.
But due to having used vane type turbine, the exhausted temperature of discharge is higher, it is necessary to come cold using substantial amounts of cooling water
But, so its disadvantage is thermal efficiency of cycle than relatively low.Compressor employs axial-flow type or centrifugal-flow compressor, volume ratio compared with
Greatly, and immovable and speed governing is rotated, only make fixed commercial electricity production device at present and use.Disadvantages mentioned above limits closing type gas combustion
The gas-turbine of turbine installation plays technical advantage in other side purposes.
In a kind of method for improving turbine engine efficiency of number of patent application 201410415779.3 and its device, patent Shen
The replacement of screwed pipe rotor please be all employ in the related application such as number 201610813636.7 a kind of screwed pipe rotors and its engine
Heat energy is converted to mechanical work by the vane type turbine rotor of prior art gas-turbine unit to improve thermal efficiency of cycle, is constituted
Using air as working medium, the combustion gas screwed pipe rotary engine of open loop type thermodynamic cycle is worked in, they must be from internal-combustion side
Formula is heated to working medium, and the source fuel selection to heat energy has certain limitations.How the technology of closed cycle gas turbine engine device
Advantage is combined with the technical advantage of combustion gas screwed pipe rotary engine and brought into play, and composition is a kind of to overcome above-mentioned technical problem
Closing type gas combustion screwed pipe rotor engine unit is the problem to be solved in the present invention.
