Abstract
A burner, process and furnace are provided for regenerating a spent acid stream or other sulfur-containing stream by decomposing the spent sulfuric acid stream and/or other sulfur-containing stream to recover sulfur dioxide from the stream. The burner includes a burner body, and at least one spent acid feed passage positioned at least partially within the burner body or other sulfur-containing feed passage positioned at least partially within the burner body. At least one fuel feed passage may be positioned at least partially within the burner body. A related process and furnace are also provided.
Claims25
A burner for a furnace, comprising:
- a burner body;
- at least one combustion fuel feed passage positioned at least partially within the burner body;
- an air inlet in fluid communication with the burner body;
- and
- at least one spent sulfuric acid feed passage positioned at least partially within the burner body.
A process for decomposing at least one of a spent sulfuric acid feed comprising:
- supplying a combustion fuel to a furnace interior through at least one combustion fuel feed passage that is at least partially positioned within a burner body, the at least one combustion fuel feed passage having an end opening into an atmosphere at the furnace interior;
- supplying atmospheric combustion air or oxygen-enriched atmospheric combustion air into the furnace interior through an air feed passage at least partially positioned within the burner body;
- and
- supplying at least one of the spent sulfuric acid feed into the furnace interior through a spent sulfuric acid feed passage that is at least partially positioned within the burner body, the at least one spent sulfuric acid feed passage having an end opening into the atmosphere at the furnace interior.
A furnace, comprising:
- a housing having at least one side wall and an interior;
- and at least one burner engaged with a side wall of the furnace and in fluid communication with the interior of the furnace, the at least one burner comprising:
- a burner body;
- at least one combustion fuel feed passage positioned at least partially within the burner body;
- at least one atmospheric air passage positioned at least partially within the burner body or at least one oxygen-enriched atmospheric air passage at least partially positioned within the burner body;
- and
- at least one spent sulfuric acid feed passage positioned at least partially within the burner body.
