Abstract
The scientific community is concerned with preserving the environment, to prevent general life degradation. Nowadays, it is evident that such an aim cannot be achieved without the aid and development of new and clean technologies. Biomass, is probably, the main weapon in this crusade, given that: residual biomass is renewable, it is a low carbon source of fuel, it is cheaper than the fossil fuel, and it is available in many countries like Brazil (Noguera, 2012). On the other hand, gasification is one of the most efficient processes to turn the internal energy of biomass available, requiring a relatively simple technology. In the present work a co-current open top downdraft gasifier, having a 4 kW thermal power capacity is used. The poor gas from the gasifier fuel an 18 Hp Otto cycle engine, is coupled to an electrical generator. In order to improve the knowledge of parameters related to the performance of a biomass gasifier, the present paper discusses the importance of the size of the wooden pieces, which fuel the gasifier, on the system global efficiency. It was noticed that the maximum value of the temperature of the reactor combustion zone was a consequence of the biomass in Sample 4.
