Process for the thermal treatment of ammonium sulfate containing wastes especially ammonium sulfate containing waste-waters

摘要

A process for the thermal treatment of wastes by injection of the wastes, via a nozzle/burner system, comprising a burner and a centrally seated atomisation nozzle, into an adiabatic combustion chamber with the use of a carrier fuel and a suitable oxidant depending on the type of combustion conditions, characterised in that under reducing and/or oxidising reaction conditions at temperatures between 600 DEG C and 2000 DEG C - in particular temperatures between 900 DEG C and 1100 DEG C - the nitrogen bound in the ammonium sulphate is principally converted into nitrogen (N2) and not into nitrogen oxides (NO, NO2) with simultaneous recovery of gaseous sulphur compounds (SO2, SO3, COS, H2S etc.).
