Abstract
A review of existing Standards for construction and operation of incinerators indicates two potentially important omissions. There is no requirement for minimum combustion intensity (though there is for a maximum), or alternatively for minimum overfire jet momentum to ensure adequate mixing and maintenance of proper overfire combustion. Neither is there any requirement for control of bed depth. Though generally less important than overfire air pressure, improper depth control can lead to intense smoke generation at one extreme, or to chanelling and underfire air bypass with excessive grit pick up at the other extreme. The review is basedon examination of the Standards from the point of view of fundamental combustion behavior. The analysis and discussion includes a general qualitative description and incipient physical model of combustion processes in an incierator, with some components of the model also quantified, notably the combustion intensity and burning rates in the bed. The discussion is directed towards factors involved in reducing air pollutant emissions.
