Professor Nimmo's background is in chemical and combustion engineering having gained his PhD in Fluidized Bed Waste Gasification Processes at Leeds University in the mid 1980’s. A period in industry followed, working on full scale coal gasifier development (350 tpd) for British Gas, Westfield Development Centre, Scotland, as part of the British Gas SNG programme in partnership with Lurgi GmbH. Projects involved the study of fuel bed behaviour at full scale and process development for operation with caking and difficult coals. Other projects involved commissioning and operation of pilot plant associated with gas clean up and upgrading to substitute natural gas using real syn-gas from the full scale plant.
Returning to Leeds, Bill pursued a number of research projects related to coal, gas and oil combustion and gasification as a Senior Research Fellow with particular emphasis on NOx, and SOx emission control in partnership with major UK power generation companies. Recently, Bill’s research activities have been closely related to the development of the UK national UKCCSRC PACT facilities focused on carbon capture processes and in particular to pilot scale oxy-fuel combustion projects. Additionally, significant research activity has been developed in the areas of fluidized-bed biomass combustion, corrosion associated with biomass and oxy-fuel combustion and small scale anaerobic digestion systems for both urban and rural locations in developing countries. He was appointed Associate Professor and since 2009, he has contributed to research projects with a total value in excess of £7m as principal or co-investigator.
Bill joined the University of Sheffield in February 2015 and has since attracted new funding with a value of £1M (£3.1M total) with 7 active research grants in the areas of ultra super-critical fluidised bed combustion, anaerobic digestion, energy from waste and knowledge economy partnership (KEP) funded by EPSRC, Innovate UK/EPSRC/BBSRC, Royal Academy of Engineering and the British Council. Bill’s other funded activities are in the areas of pulverised coal/biomass oxy fuel combustion and corrosion studies related to future advanced power generation developments. He has published 150 papers including 78 refereed journal articles, 2 book chapters and 1 patent.
As Head of the Engineering Graduate School, Bill is responsible for leadership and management in the recruitment, training and progression of PGR students in Engineering. Bill is a member of several Departmental and Faculty and University committees.. Externally, bill is an active Member of the Fuel and Energy Research Forum, Exec. Committee, Chair of the Environ. Division; Member of the Energy Institute Yorkshire branch committee; Member of the EPSRC Peer Review College and is an Associate Principal Editor of the Elsevier journal FUEL.
Bill’s teaching activities have been closely related to his research activity and has lectured in the areas of combustion theory and design, biomass energy, CCS plant design and conventional power. A particularly rewarding and enjoyable part of Bill’s activity is the supervision and development of the research students and early career researchers working on projects within the Energy 2050 Group.
