EFFECT OF INLET AIR TEMPERATURE ON THE PERFORMANCE OF COMBINED HEAT AND POWER SYSTEM

During the operation of a gas turbine based heat and power generation system, it is found that its performance is deteriorated due to variation in Inlet Air Temperature (IAT). Operating cost is augmented in terms of fuel consumption and pollution emission. Further complexity of system analysis is in...

Popis
Shrnutí:During the operation of a gas turbine based heat and power generation system, it is found that its performance is deteriorated due to variation in Inlet Air Temperature (IAT). Operating cost is augmented in terms of fuel consumption and pollution emission. Further complexity of system analysis is increased due to interdependency of components (i.e. air compressor, combustion chamber, gas turbine, regenerator and steam generator) and parameters. Therefore, present analysis is carried out with an objective to study the effects of IAT on the system, components and parameters. Mathematical modeling based upon exergy, energy and mass balance athwart the components is simulated using computer programming tool EES (Engineering Equation Solver). From the results it is found that at higher IAT exergy destruction in the cycle is increased and concentration of CO2 and H2O is generated in such a way that specific heat (C sub( p)) of combustion gas is decreased.
