  • Problems of the application of N2/SF6 mixtures to gas

    Sep 21, 2001 · Abstract. In designing a gas‐insulated bus (GIB) using N 2 /SF 6 mixtures, there are many application problems, such as the mixture pressure needed in order to maintain the required dielectric and heat transfer performance. Problems of recycling SF 6 are also essential in applying N 2 /SF 6 mixtures. This paper presents the minimum breakdown field strength at lightning impulse and the temperature rise of the conductor and enclosure as measured for N 2 /SF 6 mixtures.

    Introduction to Gas Turbine Power PlantsMajor Parts of A Gas Turbine Power PlantThermodynamic Cycle of A Gas TurbineOpen Cycle Gas TurbineMethods to Increase Efficiency of An open-cycle Gas Turbine Power PlantChoice of Fuel in A Gas TurbineAdvantages of A Gas Turbine Power PlantThe demand for Gas power plants is increasing because of certain benefits. Natural gas is used as a fuel, other fuels can be synthetic gas (syn-gas). Just like steam power plants in which operating fluid is water and steam mixture, in gas turbine power plants, air mixture is used as a derivative fluid. In a jet engine, one side has a turbine and one side has a compressor, the air is entered in the compressor, it mixes up with the fuel, it ignites, and then it ejects it from the turbine. The turbine converts the pressure and velocity into electrical power through the generator. A major problem in the operation of gas turbine power plants that when the fuel is being ejected, its temperature is 400-500 °C, which can cause atmospheric pollution, and a lot of energy is wasted. Because of this wastage of energy, the efficiency of normal gas turbinepower plants and open-cycle gas turbines is around 20-25% which is way less than its potential, even steam turbines have greater efficiency tha...
