Heat exchanger design and optimization by using genetic algorithm for externally fired micro-turbine

E. Fanelli (ENEA)

In this study, a new configuration where syngas produced by downdraft gasifier is feed directly in an externally fired air turbine is discussed. A code for heat exchanger design was built by using Matlab, while the geometrical optimization was performed by using modeFRONTIER by imposing a multi-objective function to maximize the overall heat transfer coefficient and minimize both costs and pressure drops across the equipment.
