In the last several years, atmospheric fluidized bed combustion, AFBC, has become a commercial technology. AFBC power plants offer high combustion efficiency, control of sulfur emissions, and fuel options that are not available via other techniques. Fuel options include: high sulfur coal without the need to add an FGD system; low grade coal that has ash levels that are too high for conventional coal-fired units (mining reserves can be extended); agricultural waste that would otherwise be field burned which adversely affect air quality; waste from the wood products or construction industries that would otherwise be landfilled; sludge that would otherwise require processing for disposal. The utilization of some waste fuels is helping to clean our air and reduce the piles of waste that mar our landscape. Fuel selection is a major decision for the power engineer. It is the single largest item in the power plant operating budget and has a major effect on power plant economics. AFBC technology has gained a reputation for burning almost anything. Any specific unit must, however, be suitable for the application. Plant systems and the AFBC boiler itself are dependent upon an accurate assessment of the fuel, sorbent, and bed material. To a large extent, they establish plant design requirements and the types of systems/features that are provided. As a result, an early analysis of the combustion and handling characteristics of the plant's fuel, sorbent, and material should be completed. The papers in this volume describe recent AFBC projects. They include a variety of applications using coal, coal preparation waste, and agricultural waste products. The authors provide a glimpse of how AFBC technology is being commercially applied.
