EMISSION-CONTROL IN HAZARDOUS-WASTE INCIN ERATION .2. GRANULOMETRIC ANALYSIS AND PHASE-ANALYSIS

During the last years the standard of waste-gas purification in waste incineration has improved considerably. Nowadays very low amounts (<5 mg) of stack gas dusts with diameters mostly below 1 mu m are to be ex amined. As a result it is not possible to obtain satisfactory results by conventional methods of granulometric analysis and phase analysis. That is why new methods of analysis have been developed and results of analysis of stack gas dusts from hazardous waste incineration are pre sented in this article. These data can be of importance for the optimi zation of plant parameters as well as for the determination of the pro venience of harmful substances in the atmosphere. By the presented met hod for granulometric analysis it is further possible to demonstrate t hat dust is completely precipitated using the new kind of sampling fil ters as described in part 1 of this work. By using methods of phase an alysis it was possible to detect new phases which were unreported unti l now.
