Biography

Dr Liu is a Chartered (Energy) Engineer and a member of the Energy Institute. He has research expertise in coal combustion, power plant engineering, fluidized bed technology, and biomass combustion and gasification. He has designed and tested a number of laboratory-scale and pilot-scale combustion facilities in sizes ranging from a fraction of a kW to 20 MW and has extensive research experience in modelling of combustion, gasification and power plant power generation.

Past research projects include (1) Reburning for NOx emission control (Sponsor: EPSRC) (2) Strategies for reduction of nitrous oxide emissions from combustion in a circulating fluidized bed (Sponsor: EPSRC) (3) Process simulation of circulating fluidized beds with combustion/gasification of biomass (Sponsor: EU Joule programme) (4) Coal combustion in CO2 rich flue gas - an approach to industrial applications in power stations (Sponsor: EU ECSC programme) (5) Small-scale biomass-fired CHP system (Sponsor: EPSRC) (6) Geothermal heat pump (Sponsors: EPSRC/Roger Bullivant Ltd),

His current research interests concentrate on renewable energy technologies (in particular biomass technology), clean combustion and carbon abatement technologies. His on-going research projects include (1) Cleaning of product gases from biomass gasification (Sponsor: EPSRC), (2) Integrated Biomass-fuelled CHP/cooling system (Sponsor: TSB), (3) Influence of impurities on CO2 transportation/storage (Sponser: EPSRC/University of Nottingham - the Bridging Gap fund), (4) Small-scale woody and non-woody biomass pellet boiler with low NOx and particulate emissions (Sponsor: the Carbon Trust), (5) Innovative Adsorbent Materials and Processes for Integrated Carbon Capture and Multi-pollutant Control for Fossil Fuel Power Generation (Sponsor: EPSRC), (6) The Next Generation of Activated Carbon Adsorbents for CO₂ Capture in IGCC Processes (Sponsor: EPSRC).

Many of his past and present research projects involve collaborations with UK/International universities/institutions and industrial partners.
