Abstract: The influence of bed pressure was investigate by the method of experiment. Air was used as gasifying agent during the biomass gasification experiment. Analysised the inner relationship of pressure, temperature and calorific value. The study results showed that optimum pressure range was 1.6-2.9 kPa in the experimental condition. In this pressure environment, the temperature of oxide layer reached 1 000-1 300 ℃, calorific value reached 4 900-5 700 kJ/m3, tar content decreased with the increasing temperature. However the oxide layer temperature decreased when pressure drop exceed 2.9 kPa, therefore, the influence of pressure on gas quality appeared fluctuating trend, research results could provide a reference for the study on kinetics of reaction of biomass gasification.

Key words: active-air gasification, pressure drop, production gas, kinetics of reaction, calorific value
