Process for burning of sulfur

摘要

In the manufacture of sulfuric acid, elemental sulfur is reacted to by finely atomizing liquid sulfur into a vortex of combustion air and returning the atomized sulfur in the vortex during combustion, the ratio of air and sulfur supplied to the vortex being substantially stoichiometric. This ensures that liquid sulfur is not deposited on the walls of a reaction chamber or the structure of a waste heat boiler receiving gases from the combustion chamber, and minimizes generation of nitrogen oxides.
