Abstract

Method of preparing SO2 in a combustion chamber is claimed in which liquid sulphur is atomised by a jet of the oxygen to be used for the reaction with the sulphur. Part of the oxygen is preheated by recuperation of heat from the combustion chamber, any oxygen introduced at ambient temp. being fed in around the atomising oxygen jet at a distance from it. A regular fine spray of S droplets is obtd. without anomalies of operation of the atomiser. The S and the O2 form a very intimate mixt. immediately favouring a good product yield.
