Computation of Gas Turbine System as Renewable Energy Conversion Mechanisms

Abstract

In the present work thermo-economic analysis of a cogeneration cycle is carried out so that any power generation industry can choose best power generation system out of the choices available with organisation. Mathematical modeling for the cost evaluation of each component is developed and results are obtained with computational programming tool EES (Engineering Equation Solver). Form results it is being found that with change in combustion chamber outlet temperature or turbine inlet temperature from 1373 K to 1723 K the purchase equipment cost for combustion chamber and gas turbine is multiplied by 85.36 and 2041.85 times respectively. Gas turbine section and air compressor section are attached with solid shaft. The rotational speed of the both sections are same. Factors responsible for increasing the cost of gas turbine section are similar to air compressor section. For gas turbine section it is evaluated that with increase in air mass flow rate from 85 kg/s to 115 kg/s, the cost is increased by 43.72%. Therefore, with the help of the methodology present in the present work it is possible for the power plant managers to decide about the suitability in power generation capability development in association with renewable and non-renewable energy conversion systems.
