Biomass Thermochemical Conversion

 
 

Our research projects, funded by various funding organisations (Research Councils, Industry), focus on many issues (emission, efficiency, sustainability etc.) relevant to different scales of biomass utilisation, ranging from micro-scale distributed combined heat and power generation and domestic biomass boilers, to large-scale power plant applications.

In addition to a full range of analytical facilities for fuel characterisation, we also have a number of laboratory-scale research facilities including Drop tube furnaces, biomass gasifiers, a fluidised bed combustor and, as part of the Energy Research Accelerator, a pilot-plant for hydrothermal carbonisation.
