✦ Synopsis

This review contains 48 references and presents in chronological order the art of ash deposition while firing coal, the mechanistic approach to the problem, the recent introduction of sophisticated analytical procedures, and modelling of mineral transformations, and ash deposition underway. The adaptation of fuels such as ash oil, petroleum coke, municipal waste, wood and biomass to the steam raising process are presented individually in the order in which they were introduced. Empirical indexes currently used to characterize the slagging or fouling potentials of impurities in fuels are given and fundamental data are provided where necessary to illustrate the mechanisms for ash deposition.
