Flue Gas and Fly Ash, edited by P.F. Sens and J.K. Wilkinson, Proceedings of
a contractors meeting organized by the Commission of the European Communities, Directorate-General for Science, Research and Development, Brussels, Belgium, June 16, 1988, Elsevier Science Publishers Ltd., Barking, ISBN 1-85166-324-X, 182 pp., £ 24.00 (ca. US$ 36). This book contains 14 presentations dealing with environmental aspects of flue gas and fly ash. Each report is a summary of the current status of 2 to 3 year contracts, the majority of which began in 1986. Thus, most projects are nearing completion and pertinent results have been included in the reports. The book is divided into two sections: Section I summarizes research on flue gas treatment and Section II contains work on fly ash properties and use. Nine contract updates are presented in the flue gas treatment section including topics on NO~ and S02 control and particulate removal. Specific work on catalytic NOx reduction is aimed at developing a cost effective modified SCR process; the work on sulfur reduction involves developing regenerative SO2 processes mainly for fluidized bed combustion (FBC) systems. The particulate removal papers include work on elimination of smoke/soot particles before complete combustion occurs, such as in fireplaces or stoves. These processes require very low pressure drop filters which are able to withstand high temperatures. Methods to efficiently separate solids, at both high and low temperatures, from FBC units are also presented in some of the papers. Additionally, pulse power techniques to improve conventional ESP performance is discussed and results are presented from an industrial-scale test (35 MWe) showing the benefits and economics of pulsed power. Section II of the book contains five presentations of fly ash characterization mainly dealing with leachability and long term disposal. The focus of these papers is to determine which, if any, elements or compounds might be leached from coal ash during long term storage. One interesting presentation discussed the possible use of fly ash as a filler in polyurethane insulation foams. While fly ash additions up to 30% reduced some foam properties, it did improve the fire properties of the foam. The book contains general conclusions of these studies and recommendations for future work in the fly ash and flu gas treatment areas. It will benefit those who are involved in fly ash disposal and in flue gas treatment particularly from FBC systems. The book is neatly printed and all tables and figures are clear. N.S.
