Gas turbine
InactiveCN103415684AImprove rotational energy conversion efficiencyReduce manufacturing costGas turbine plantsStatorsManufacturing cost reductionFlow resistivity
The present invention relates to a gas turbine. According to the present invention, gas may be injected in the circumferential direction in order to rotate the turbine shaft using a repulsive force, thereby improving the efficiency of the conversion of rotational energy of the turbine and reducing manufacturing costs. Also, the flow resistance to the gas may be reduced, pressure leakage may be prevented, and energy loss may be reduced so as to manufacture an inexpensive turbine having high efficiency. In addition, when turbines having capacities different from each other are manufactured, parts may be easily shared with each other, and the eccentric rotation of the turbine shaft may be prevented to significantly improve durability. Also, an air compression part, a gas expansion part, and a power generation part may be modularized, and fuel and water may be supplied together. Thus, overheating of the gas expansion part may be prevented to prevent air from being excessively expanded, and vapor may be generated to improve rotational force in addition to the impellent power of the turbine. Also, the gas turbine may be manufactured using a relatively inexpensive metal material instead of expensive high temperature ablative materials in order to reduce manufacturing costs.
