A highly efficient apparatus for burning sulfur to sulfur dioxide and generating sulfurous acid comprises a primary sulfur-burning chamber, a sulfur feed tank closely coupled to the primary chamber, a secondary sulfur-burning chamber, and an absorption tower. The conduit connecting the sulfur feed tank and the sulfur inlet of the primary chamber may have a cross sectional area of at least 15% of the surface area of the pool of molten sulfur in the primary chamber and a length less than the diameter of the pool. Air is introduced to the primary chamber under turbulent, high-velocity flow conditions. Gas passes through the secondary chamber under turbulent flow conditions. |
