Performance of diesel cycle engine-generator operating on dual fuel mode with gasification gas

Abstract

The Brazilian Federal Government aims to expand the electrical energy supply to the low income Brazilian citizen through Light for Everyone Program. The objective of this study was to use the program as a vector of social and economical development. One of the obstacles was to reach even the isolated communities. In this work, the performance of a cycle diesel motor generator running in dual mode, diesel and gasification gas, as an option for decreases, the dependence on diesel by the isolated communities was evaluated. The process was based on obtaining gas through the partial biomass burn, which in high temperatures is converted to fuel gas that may be used in internal combustion engine. Among the results, it was observed that there is a reduction of 30.7% in the diesel consumption, a better voltage adjustment and a maximum current at the generator, leading to a power increase of 43.8% saving R$ 0.86 for each kW h^-1. These results show the possibility of using the biomass gasification to decrease the diesel consumption to produce electricity in the isolated communities.
