✦ Synopsis
chemical moved through oxidative volatiies pyrolysis, volatiles combustion, soot combustion, and char oxidation. However, only with the low volatility coal were the different fuel components consumed sequentially. Char, soot, and non-condensable fuels burned simultaneously with the sub-bituminous coal and, to a lesser degree, with the Pit. #8. Consequently, hydrocarbon gases from these coals were present while most of the soot and char was converted into gases. 9aloo523 Co-combustion of sewage sludge in a lignite-fired industrial power station Bierbaum, K. et al. Chemical-Ing.-Tech.. 1997, 69, (7), 973-976. (In German) A summary of the operation of a large-scale test about co-combustion of mechanical dehydrated sewage sludge in a circulating fluidized-bed steam generator. A plant concept consisting of steam generator, units for sewage sludge deliverance and flue gas fine cleaning is introduced. The advantages of sewage sludge co-combustion are valued under aspects of energy balance, environmental protection, reduction of costs, and restrictions of recycle and waste orders.
