A Regenerative Limestone Process for Fluidized Bed Coal Combustion and Desulfurization.

摘要

An experimental study was conducted on a fluidized bed coal combustion system using lime as a bed material. The lime reacts with SO2and O to form CaSO4under oxidizing conditions,thus reducing SO2emissions. The reductive regeneration of the sulfated lime back to CaO2and recycle of the regenerated lime back to the combustor was investigated as a method of reducing fresh limestone feed rates to the system. A three inch diameter combustor and a two inch diameter were utilized in this experimental program. (Author)
