The operation of the gas turbine to determine the method of initial temperature

Death turbine exhaust gas temperature, it also needs to know the gas turbine isentropic efficiency, gas turbine inlet pressure loss rate, chamber pressure loss rate, exhaust pressure loss rate. Since these parameters during normal operation of the unit changes with the magnitude of the load is not large, so may take the values provided by the manufacturer. In this method to determine the initial temperature is above the second definition given in the initial temperature of gas turbine, which turbine first stage nozzle stagnation after the average temperature. 5 Method IV: Gas turbine power generation system gas turbine power generation systems and power balance the power balance equation: 3600Pe = {(G + elbow). [(T3) A (T4)]-Wc}. m. . (9) where: P. - Power Generation (kW); knock. - Generator efficiency (%); call-in - mechanical efficiency (%); G - the amount of air entering the combustion chamber and into the gas turbine and the amount of cooling air (kg / h); - Compressor Power consumption. When given power output, the generator efficiency hatred, power and mechanical efficiency of call-in gas turbine compressor exhaust temperature, according to equation (9) can be obtained by importing gas turbine enthalpy (), and to determine the initial temperature of gas turbines. Among them, the compressor power consumption of a 1:! KJ / h (10) c In this method, the total gas turbine power generation system prevail, we have considered the impact of turbine cooling air. Therefore,ugg boots sale, the calculated initial temperature is the third definition given in the initial temperature of gas turbines, that all the air into the gas turbine flow calculation, the average temperature. In addition, the calculation involves the compressor isentropic efficiency, the application of the method to determine when the initial temperature of gas turbine compressor is in normal working condition requirements. 6 Conclusion The above analysis shows that the initial temperature of gas turbine operation can not be directly measured in the case can be based on other parameters obtained by theoretical calculation. However, no matter which method involves direct measurement of some data and equipment performance data. These data error in the computation process may be enlarged, so ultimately the initial temperature of gas turbine errors. Therefore, to ensure the accuracy of calculation,GHD glätteisen günstig, one needs to ensure the accuracy of direct measurement of parameters, and the need to obtain more accurate equipment performance parameters.
