Estudio técnico económico para aprovechar los gases de escape en el enfriamiento del aire de entrada al Compresor de las Turbinas de gas Solar Centauro 50 de la Planta de generación TPP

Abstract

The Centaur 50 (C50) gas turbine nominal power output (4,4 Mw) is limited by its inlet air temperature, when it is increased also increases the temperature of the combustion chamber until the alarm or unscheduled stop condition is reached , to ensure that the above condition does not occur, the power delivered by the generation set must be reduced. To avoid this power loss, the current study aims to use the exhaust gases in a cooling system and reduce the inlet air temperature until the standard condition. The study development begins with some theoretical concepts related to the topic, it continues with the methodology used to obtain the current condition operation parameters, the work place environmental conditions and the inlet air reference conditions. These values allow us to select the components of the air-cooling system, calculate the efficiency parameters corrected at the reference temperature, and determine the project economic indicators. The obtained results shown, that by cooling the inlet air, the electric generator power output increases by 14,38 %, the heat rate decreases by 3,71 % and the thermal performance reaches 34,32 % approximately. The economic indicators show that this project is technically and economically feasible to be implemented.
