Delevopment and use of a model for incinerators of oil spills and domestic waste

Experiments in flow models have been used to study various problems concerning incineration of contaminated matter. The basic philosophies are: (1) The fixed bed of burning material in most cases acts as a pyrolyzer, and combustion is completed in the space above the bed. (2) Regardless of existing knowledge of the mechanisms for formation of various air pollutants, the task of the incinerator is to maintain certain conditions regarding the distribution of temperature, residence, time, and concentration of oxidizing agents. The consequence of this is that many problems can be solved in an efficient and cost effective way using experiments in cold and hot models. Similarity criteria and experimental methods are discussed and illustrated by two case studies: finding remedies against fouling problems in an existing incinerating plant for municipal waste, and development of a mobile incinerator for oil-contaminated solid matter
