Biomass Gasification at Mississippi State University: Preliminary Results J. Alex Thomasson Department of Agricultural & Biological Engineering Mississippi State University
Acknowledgments • USDA for funding • DOE NREL for advice and consultation • Community Power Corporation for cooperation
Outline • Overview of joint project between Mississippi State University and Oklahoma State University • Selection of Biomax downdraft gasifier • Delivery and installation at MSU • Overview of experimental runs to date • Data acquired • Temperature charts of each run • Final comments
MSU-OSU Joint Project • Approximately $1 million per year • Split between OSU and MSU • Coordinated parallel projects • Each covers several research components of a proposed system • Feedstock development • Harvesting and processing • Gasification • Microbe development • Bioreactor development • System economics
Gasification • OSU has built fluidized bed reactor; extensive work in design and construction of feeding systems • MSU started 1 year behind • MSU conducted review of literature and commercial availability
Final Comments • Control Parameters • Overall flow rate • Grate vibration • Magnitude • Frequency • Temperature settings usually are not adjusted • Temperatures are primary feedback for control • Operational status: • Gasifier can now be operated relatively repeatably with wood chips • Next steps • Refine sampling and measurement procedures for gas quality and tar • Develop standard experimental protocol • Conduct replicated experiments with various densified feedstocks
