Performance Prediction and Combustion Modeling of Low-CO2 Emission Gas Turbines

Abstract

The authors present a comprehensive analysis of innovative solutions for reducing the CO2 emission from gas turbine based power plants. Two different gas turbine types are considered, first in their baseline arrangement and then with modified configurations with regenerative, water-intercooled cycles. The carbon dioxide reduction is obtained through a partial oxidation of the natural gas upstream of the combustion chamber. The analyses are carried out with an increasing level of complexity, starting from a purely thermodynamic approach and then proceeding with a component matching based method. Finally, the comparison of the CFD simulation of the combustion processes of the conventionally fuelled combustor and of the one supplied with the decarbonized fuel is presented.
