This article discusses the many and varied problems associated with coal combustion and suggests remedial measures to assist in producing electrical energy from coal more efficiently. Contents include: influence of coal mineral matter on boiler design; mineral impurities in coal; quality of coal utilized in power stations; coal grinding, abrasive fuel minerals and plant wear; particulates silicate minerals in boiler flame; reactions of nonsilicate impurities in coal flame; creation, capture and coalescence of particulate ash in boiler flame; slag viscosity; sintering, fusion and slagging propensities of coal ashes, adhesion of ash deposit on boiler tubes and refractory materials; deposition mechanisms, rate measurements and the mode of formation of boiler deposits; thermal radiation and heat transfer properties of boiler deposits; measures to combat boiler fouling and slagging; some specific ash-related problems with US Coals; use of additives in coal fired boilers; high temperature corrosion in coal-fired plants; ash impaction erosion wear; low temeprature fouling and corrosion; comparison of ash-related problems in pulverized fuel and other coal-fired systems.
