Verfahren und Vorrichtung zum Desodorieren und Reinigen von von der Verbrennung von nassem Abfallschlamm herrührenden nassen Abgasen bei mittelmäßiger Temperatur

摘要

Medium temperature (500 DEG F.-1100 DEG F.) wet off-gases from the final drying zone of counterflow incineration of waste sludge are scrubbed and cooled before heating to final high temperature in an afterburner and the resulting hot dry gases are used to preheat the scrubbed and cooled gases prior to entry of said gases into the afterburner.
