Show IJrnuiden October 1987 - 5 - Waste Incineration . Technology Highly variable and heterogeneous waste materials result in several operating problems which, the respondents agreed, may be reduced by improved incinerator design. There were no examples cE design improvements in the responses - a task which was suggested for the workinq group. Identification, measurement and control of pollutant emissions from various wastes is an area of potential research. Important emissions from waste incinerators include odours, smoke, particulates, polynuclear aromatic hydrocarbons, NOx, SOx, metals, dioxins and other halogenated hydrocarbons. Further improvements in equipment design to make in-flame measurements of these species are necessary. These measurements could lead to improved incinerator design by identifying the effect of operating parameters on emissions. It was agreed that a working group on waste incineration would be useful in defining the "research opportunities and requirements i n member countries. However, a detailed review of current incinerator design and operating problems was suggested. From this review, the working group could define research options for consideration by the members. 2.2 FORMATION OF A WORKING GROUP The results of the questionnaire were summarised and presented to the Joint Committee. It was recommended that a Working Group be formed to determine the research options in waste incineration. An inaugural meeting of the waste incineration working group was held in Sheffield, England in April 1987. Prof. R Collin was nominated as Chairman and Mr K J Knill as Technical Secretary_ Representatives from the academic, industrial and government communities in England, Sweden, Federal Republic of Germany and the Netherlands formulated the objectives of the Working Group_ Based on the response from the questionnaires, it was agreed that the principle objective of the working group should be to co-ordinate research interests in the member countries. As several other research organisations exist to study problems of waste disposal, this working group would concentrate on defining research requirements related to characterisation of the combustion properties of waste, flame properties and emissions, combustor design and operation. It was noted that objectives may need to be defined separately for industrial, hazardous and residential wastes since problems related to these two sources may be very different. In order to define research options for the Foundation, a detail ~ c review of the above stated aspects of waste incineration |
