The present Combustion File is part of the cluster of CFs produced within the literature survey phase of the industrial sponsored research and development project PowerFlam1 and is confidential to the participants registered for that project.

This CF is specifically concerned with the research project:

M. Tamura and W.L. van de Kamp. (2001): Characterization of Alternative Fuel for Blend with Pulverised Coal, which is published within The Sixth International Conference on Technologies and Combustion for a Clean Environment, Cleanair. Oporto, Portugal. 9-12 July Vol II

2. Background

·         This combustion file is concerned with the provision of combustion related data to the sponsors.

·         In this html file the source of the data is summarised in section 4 below, in order to give the reader a general overview of the way the data was collected.

·         Fuel and related data, prepared for calculation, are presented in individual Microsoft Excel Worksheets, all contained within a Workbook.

·         Please note that in some cases, the worksheet tabs within a workbook are not all visible without scrolling horizontally.

·         This workbook can be down-loaded by the reader and saved to her/his hard disk.

·         To achieve this click on the “xls” icon on the left hand side of the banner above. The file will be retrieved from the server, and with up-to-date versions of the browser, will appear in a separate window, from which it may be saved to the user’s hard disk.

·         The data in these worksheets are protected – thus the reader cannot change the worksheet without knowledge of the protection password.

·         However the reader can copy and paste the data into his/her own project work book as required – at this point the accuracy and integrity of the data becomes the responsibility of the reader. Included in this workbook are copies of the abstract and synopsis for reference purposes.

3. Abstract

Reducing the greenhouse gases becomes now the centre of public concern. A large portion of the greenhouse gases is discharged from power industries, especially from coal fired plants. Thus power producers have to find the solution to this. Utilisation of alternative fuels (so-called biomass) for electricity production is one of most realisable and economic ways of achieving CO₂ reduction. Technical information on combustion of pulverised coal has been accumulated over the last decades. The methods of burner design, operation and methodologies of pollutant emissions have been well established. However the co-firing behaviour of biomass and coal is not yet well understood. This study evaluates the effects of alternative fuels blended with pulverised coal on combustion characteristics in an Isothermal Plug Flow Reactor (IPFR). The aim of the experiments was to assess whether the combustion behaviour of co-firing could be predicted from that of the parent fuels. Several alternative fuels such as paper sludge, pure wood and plant substrates were selected and characterised.
