Resumo:
This thesis includes the feasibility study, technical and economical, of a new power generation system that combines two technologies: Gas Microturbines GMT and Biomass Gasifiers. The response of a microturbine to gas with nominal power of 200 kW being fed with synthesis gas is studied; two specific types of gasifier are analyzed: Downdraft Gasifier DG and Dual Fluidized-Bed Gasifier DFBG, both operating with a reference biomass (wood pellets) and using different gasification agents (air, steam, oxygen and mixtures thereof). Finally, the behavior of both technologies when coupled is validated through simulation. The delivered electric power ranges from 52.51 kW to 56.73 kW depending on the type of gasifier and the gasification agent used. The overall efficiency of the arrangement may vary between 4.64 and 11.01%. From the economic assessment, none of the technically possible systems is viable.
