ABSTRACT OF THE DISCLOSURE A method for producing an oxide of sulfur using pressurized air. The pressurized air is mixed with molten sulfur at a sulfur burner to ignite and combust the molten sulfur and form a reaction mixture. The molten sulfur may be atomized. The pressurized air may be divided into two portions, one of which is preheated. The unheated pressurized air is mixed with the reaction mixture in the sulfur burner downstream of the location where the preheated pressurized air is mixed with the molten sulfur. Combustion of all the sulfur to sulfur dioxide is essentially completed within the sulfur burner, and the temperature of the gaseous mixture leaving the sulfur burner is controlled. The sulfur dioxide may then be cooled and converted to sulfur trioxide in a catalytic converter. The Moisture content of the pressurized air is reduced in a pressurized dryer upstream of the sulfur burner.
