An improved apparatus for burning sulfur to sulfur dioxide and generating sulfurous acid comprising a primary sulfur-burning chamber, a sulfur feed tank closely coupled to the primary chamber, a secondary sulfur burning chamber, and an absorption tower, Air is drawn into the primary chamber under turbulent, high velocity negative pressure conditions. Gas passes through the secondary chamber under turbulent negative pressure flow conditions. The apparatus is capable of converting sulfur to sulfur dioxide at a rate in excess of 25 pounds of sulfur per hour per square foot of surface area of the molten pool of sulfur in the primary chamber.
