The results of an inquiry in 1997 show that the percentage of sewage sludge disposed of by incineration in Germany is 19%. Legal developments in Germany clearly show that this percentage amount is expected to increase in the next few years. According to legislation, the treatment of the sewage sludge will have to achieve a result of {le}5% combustible (according to TA-Siedlungsabfall, i.e., Technical guideline for handling and disposal of urban waste). Sewage sludge incineration will therefore become a preferred treatment process. Fluidized bed combustion is especially suitable in relation to the burn-up results. Around 19 sewage sludge incineration plants are operating in Germany, 17 of which have stationary fluidized bed furnaces, the others are multiple hearth roasters. The German statutory law affecting emissions from sewage sludge incineration plants is 17.BlmSchV (i.e., Paragraph 17 of the Federal Emissions Control Regulations). These regulations stipulate mandatory compliance with limit values as a daily average value figured in standard conditions. The intention is to build up an overview of the various possibilities to reduce the NO{sub x} emissions from one problematic industrial sludge by using primary measures, and if possible, to avoid expensive secondary measures, like the SNCR (selective non catalytic reduction) or SCR (selective catalytic reduction) processes.
