ABSTRACT

Cuba has forestry industry residues gasification plant for at the "Gran Piedra Baconao Integral Forestry Company" in Santiago de Cuba, which includes a gasifier, internal combustion engine, and a wood dryer, that uses residual energy from the engine. In this work, an experimental theoretical evaluation of the cogeneration indices of the installation is carried out. The evaluation was carried out from mass and energy balances in the equipment that make up the installation from an experimental database resulting from 1194 hours of work of the, electrical energy generating for the sawmill and the national electrical network. The evaluation showed an electrical energy production efficiency of 11,07 %, a total cogeneration electrical efficiency of 41,94 %, and a net electrical energy production efficiency of 20,30 %. Other cogeneration indicators determined were net heat index of 4,93 kW/KW and renewable energy produced-fossil energy consumed ratio of 4,18.

Keywords : biomass; gasification; electricity.
