Combustion in an incinerator occurs in two dif­ ferentiated zones: (1) the solid bed, Zone I, where the principal processes are pyrolysis, gasification, and combustion, and (2) the overbed region, Zone II, where the principal processes are flame holding and final burnup. Equations are developed to relate com­ bustion intensity in each zone independently to the average combustion rate in each zo...

3333679 37 6 $ E The Effect of Kiln Temperature on DRE and Organics Concentrations in Incinerator Ash W. R. Schofield, PhD, PE; W. V. Walls, PE; and Thomas Jones Chemical Waste Management, Inc. (CWM) conducted RCRA and TSCA trial burns on the world-scale hazardous incinerator a t Port Arthur, Texas, in early 1990. Subsequent commercial operation revealed start-up problems which included (1) com...

The object of this paper is to throw light on the criteria which apply to the degree of burn-out on a furnace burning mixed household and trade refuse. In particular, the paper concentrates on the ash discharged from the end of the grate since this represents the bulk of the ash produced by the plant. The classical approach to burn-out is to employ "carbon-in-ash" techniques familiar to combust...
