Mechanical Engineering senior, Kyle Pace, evaluates the flame temperature and composition of combustion products produced using a student-built wood gasifier. An important renewable energy technology, wood gasification extracts combustible fuels such as hydrogen and methane from wood and other biomass feedstock through controlled application of heat. In this laboratory experiment, students demonstrated that wood gasification enables nearly complete fuel utilization, leaving less than 1% of the fuel mass as unburned ash.
