Resumo
The EFGT cycle has been considered as an option to burn biomass in gas turbines. One key element on the implementation of one EFGT cycle is the ceramic heat exchanger necessary to support the high temperatures of operation. The performance of the ceramic heat exchanger, its effectiveness and pressure drop imposed to the gas flow, may have significant influence over the thermal efficiency of the EFGT cycle. The simulations of the EFGT cycle presented herein use correlations for the pressure drop and heat transfer of one ceramic heat exchanger of the plate and fin type, evaluated numerically. The results obtained show that the type of ceramic heat exchanger simulated presents adequate performance to be implemented in one EFGT cycle.
