Abstract
Greatest interest to solve problems of the thermal utilization of wood biomass are thermochemical conversion techniques based on gasification to produce heat and electricity. In this work a methodology for evaluating the efficiency of energy conversion during the gasification of woody biomass using methods of thermal and thermodynamic analyze is presented. The thermal and exergetic balances are compiled, the thermal and exergy efficiency of gasifiers is determined; thermal efficiency values range from 40.4 to 96.7 %, exergetic efficiency - from 17.0 to 58.2 %.
