Welcome to the Biomass Gasification Group at DTU

 

Since 1989 the Biomass Gasification Group (BGG) of the Department of Mechanical Engineering at The Technical University of Denmark has carried out research in thermal gasification of biomass as well as end uses of the product gas for heat and power.

 

The activities include research, development and teaching.

 

Fundamental theoretical know-how has been developed and a significant base of practical experience has been established. A number of instruments and dedicated test stands have been developed. Also a number of computer-based simulations tools have been developed.

 

The aim of the activities is to contribute knowledge as well as experience to the development of technology for thermal gasification of biomass and end-use of bio-syngas, e.g. gas engines, stirling engines, steam turbines, gas turbines, fuel cells and production of liquid and gaseous bio-fuels such as methanol and DME. During the years the MEK have contributed by defining and studying new processes and by developing new simulation tools. The established knowledge aims towards the solution of general as well as specific problems related to gasification and used pilot and development projects.

 

BGG is working with several gasification processes at our premises:

• The Viking gasifier is an unmanned, automated and essentially tar free gasifier plant with an integrated gas engine for heat and electricity production based on the two stage fixed-bed gasification process and fueled by wood chips. Until now it has produced electricity from wood chips for 3200 hours.
• The LT-CFB gasifier (Low-Temperature Circulating Fluid Bed) is a 500 kW gasifier for difficult fuels with high alkali contents. Until now it has successfully been operated on straw containing more than 12% ash, pig manure and chicken litter. Also its smaller 50 kW predecessor is still operational.
• The Low-Tar BIG gasifier is a new fluid bed implementation of the low tar two stage gasification process intended for large scale two stage gasification plants.
