Gas Turbine/HRSG Co-generation Cycle Performance Evaluation and Enhancement

Abstract

The project has two major units in it, namely ‘Gas Turbine’ & ‘HRSG’. The former utilizes natural gas, post combustion as is fuel, which in turn rotates generator having a capacity of 9MW, whereas the latter employs the exhaust gases coming out from the gas turbine to generate the steam needed in the process called ‘steam reforming’. Our aim is to enhance the efficiency of this whole unit, in order to do so, we will lower the temperature of exhaust gases via adding an additional unit to exchange heat with flue gases, as there is still some potential in the gases going into the atmosphere. Doing so will not only enhance the efficiency of the whole process but also will lower the cost per unit of electricity generated.
