ABSTRACT:
There is disclosed a process for the combustion of H.sub.2 S containing gases with air and/or oxygen into elementary sulfur and separation of the sulfur from the reaction gas, in a load range from between 100 and 5%. The process takes place in a combustion zone equipped with burners, an adjoining reaction zone and several cooling zones, in which--possibly after previous reheating and further catalytic transformation into sulfur--the sulfur formed condenses and is then separated. The H.sub.2 S containing gases are supplied to the combustion zone by one or several main burners in the high load range and by a by-pass burner in a low load range. In the low load range, a heating gas is also burned by a separate burner and the cooling surfaces in the cooling zones which are coated by the reaction gas are reduced.
