Summary on Grant Application Form |
|
This proposal forms part of a much larger nation-wide research programme, involving industrry and academe, concerned with the abatement of NOx emmissions from pulverised coal fired boilers by aerodynamic means. The overall objective is to assess and predict the NOx emmissions and carbon burnout characteristics for a range of indigenous coals when fired in utility boilers employing a variety of low NOx technologies. The whole project, with its many proposed industry and academic partners, was originally conceived in orded to revitalise the considerable wealth of UK expertise and talent in the wake of privatisation and other reforms such that the country could maintain its competitive position in the world market. Further information on the scope and content of the whole programme is provided by the covering document prepared by National Power plc, the industry consortium member charged with overall co-ordination.The present application relates to research to be performed jointly by the ICSTM and the University of Leeds and targets both experimental and mathematical modelling tasks. The foundation of the former is based upon in-flame data of velocity taken in the Mitsui Babcock 150kW large scale laboratory furnace and combustion data for several coals supported by an existing EPSRC project taken in a similar size furnace at ICSTM. The mathematical modelling effort concerns: validation of a fluid dynamic model against velocity data from one of the industrial partners, followed by a developement of a reduced chemistry N-H-O- hydrocarbon scheme; soot/NO interaction schemes; char-NO formation and destruction schemes; integration of these into an NO post-processor; integration of the post-processor in 2-D and 3-D codes; validation of the resulting packages against the above-mentioned 2-D experimental data; and, finally, against 3-D data which will be obtained in the 1MW furnace of PowerGen. The individual project objectives of the two academic collaborators are presented in Section 6 of their respective EPS(RP) FORMS.
