Experimental Study on Continuous Gasification Characteristics and Mechanism of Pine with Air/Steam

Abstract:

Biomass gasification is influenced by many factors, such as temperature, air equivalent ratio, steam/carbon mole ratio, etc. Mostly, these factors are affected each other during the gasification process. It is needed to study the gasification characteristics and the action mechanism of each factor. Firstly, a moving gasification bed is adopted to investigate the biomass gasification characteristics and mechanism in this paper. The pine sample is evenly distributed in a long tray and be sent into the furnace at a certain speed. At the same time, with a furnace temperature, linearly increasing from the entrance to the center of the furnace, the pine sample can be gradually heated up. Based on these, the experimental studies of pine gasification on different ER (air equivalent ratio), S/C (steam /carbon mole ratio) and the temperature T are carried through in this paper. The gas production rule and low calorific value of the syngas have been gotten with heating rate 25°C/min. At last, this paper gets the kinetic parameters of air gasification with different ER.
