Abstract
This invention describes a sulfurous acid generator that employs a burn chamber that acts as a sulfur hopper. Generally, the burn chamber is not in sulfur communication with a sulfur hopper that is separate and distinct from the burn chamber. Instead, the burn chamber may be adapted to hold enough sulfur to allow the generator to produce sulfurous acid for a desired period of time without needing more sulfur to be added to the sulfur being combusted in the burn chamber.
