APPLIANCE TO BURN SULFUR APPLIANCE TO GENERATE SULFURIC ACID APPLIANCE TO PRODUCE SULFUR DIOXIDE BY SULFUR BURNING CONTINUOUS PROCESS TO PRODUCE SULFUR DIOZIDE AND CONTINUOUS PROCESS TO PRODUCE SOULFUR ACID

摘要

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.
