Description:
Biomass can be gasified to yield synthesis gas, tars, and ash. The process is governed by a number of parameters such as the temperature of the gasifying medium (in this case air), and the moisture content of the feedstock. Synthesis gas from gasifying wood pellets was collected and analyzed as a function of inlet air temperature and feedstock moisture content. The air was introduced at temperatures ranging from 630 to 730 degrees C and the moisture content of the feedstock ranged from 8 to 20 percent. The data collected was used to establish the relationship between the outcome of the gasification and these two parameters, and then to determine optimal operating parameters for maximizing the fuel value (maximizing the concentration of flammable gases in the synthesis gas) while minimizing the production of gasification tars.
