Book excerpt: A development program on pressurized fluidized-bed combustion is being carried out in a bench-scale pilot plant capable of operating at 10-atm pressure. The concept involves burning fuels such as coal in a fluidized bed of particulate lime additive that reacts with the sulfur compounds formed during combustion to reduce air pollution. Nitrogen oxide emissions are also reduced at the combustion temperatures used, which are lower than those used in a conventional coal combustor. The CaSO4 produced in the combustor is regenerated to CaO that is recycled to the combustor for removal of sulfur compounds. Information is presented on the effects of coal and additive particle size on SO2 and NO emissions, one-step regeneration of sulfated limestone, laboratory-scale experiments on the reaction of calcium sulfide with calcium sulfate, volatile constituents in the effluent gas from coal combustion, properties of a dolomite bed of a range of particle sizes and shapes at minimum fluidization, and the status of separation of the combustion system and regeneration system.

This book was released on 1975 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using fluidized-bed combustors in power and steam plants is being evaluated. The concept involves burning fuels such as coal in a fluidized bed of either a naturally occurring, calcium-containing limestone or dolomite or in a synthetically prepared calcium-containing stone. The calcium oxide in the stone reacts with the sulfur released during combustion to form calcium sulfate, which remains in the bed, thus decreasing the level of SO/sub 2/ in the flue gas. Levels of NO/sub x/ in the flue gas are also low. The effect of operating variables and type of stone on the levels of SO/sub 2/ and NO/sub x/ is being determined. Behavior of trace elements during combustion has been preliminarily evaluated. The properties of a fluidized bed at minimum fluidization at different temperatures and pressures have been determined. The CaSO/sub 4/ produced in the combustion process is regenerated to CaO for reuse in the combustor by reductive decomposition at 1095/sup 0/C (2000/sup 0/F). The effects of operating variables on sulfur release during regeneration are being evaluated. Another regeneration process, solid-solid reaction of CaSO/sub 4/ with CaS, is also being investigated. Fundamental investigations of the kinetics of sulfation and regeneration reactions for the natural and synthetic stones are continuing. A model for the sulfation reaction is presented. The status of the new combustor andancillary regenerator equipment is discussed. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: This work supports the development studies for atmospheric and pressurized fluidized-bed coal combustion. Laboratory and bench-scale (process development) studies are aimed at providing needed information on limestone utilization, control of emission of alkali metal compounds and SO/sub 2/ during combustion, particulate loadings of flue gas, and other aspects of fluidized-bed coal combustion. Characterization of a variety of limestones and dolomites from various parts of the United States for suitability for use in fluidized-bed combustors for SO/sub 2/ emission control is also being done. Reducing the volume of solid wastes to reduce their environmental impact is a major goal. The development of methods for controlling the composition of hot flue gas so that it is a suitable feed gas for gas turbines is another major aim. These studies are designed to supply data and new concepts essential for the timely application of fluidized-bed combustion units to public utility and industrial systems.
