Low Carbon Energy and Resources Technologies Research Group

Combustion and Cleaner Coal Technologies 

The research programme on ‘Combustion and Clean Coal Technologies’ mainly focuses on the study of combustion fundamentals, CO2 capture, control of NOx and SO2 emissions and the removal of multi-pollutants such as mercury etc. Past and current research projects encompass both pulverised fuel combustion and fluidised bed combustion of coal, biomass and co-firing.

In addition to a full range of analytical facilities for fuel characterisation, we also have a number of laboratory-scale research facilities including three Drop Tube Furnaces which can be used to study pf combustion and particle ignition and Small Pilot-Scale Fluidised Bed Combustors.
