Review of slagging and fouling from low-rank coals; plant survey, bibliography, and discussion: Volume 2 bibliography and discussion: Final report
The objective of this report is to present available information on factors relating to ash fouling and slagging when burning low rank coals in a single reference document to be used by boiler designers, plant operators and coal researchers. The report presents detailed information on coal properties, boiler design and operating experience compiled and organized into two major sections: (1) A plant survey of boiler design and operating data for units over 100 MW at selected US plants burning lignite and subbituminous coal, based on survey questionnaires and data available from the open literature. (2) An interpretive review of factors influencing the occurrence and prevention of slagging and fouling, based on an annotated bibliography dealing specifically with the utilization of low rank coals in utility boilers and related research on coal and ash properties and deposition mechanisms. We believe that the topics covered in this report will provide useful reference information to a wide audience in the US and abroad, owing to the fact that world-wide requirements for power generation are increasingly being met by low rank coals. Despite over thirty years of study devoted to slagging and fouling in burning low rank coals, major problems still exist. These problems persist in part because boiler designs and operating practices have not been sufficiently matched to the highly variable properties of low rank coals. However, progress has been made, and some recently commissioned boilers are burning coals having a very high fouling potential without significant problems. Sufficient information on design and remedial methods is available to successfully burn most highly fouling low rank coals. However, it is important that the available information be more fully utilized. 49 figs., 19 tabs.
