Sulfur-producing process and system for producing sulfur dioxide
摘要
Sulfur dioxide is formed by the combustion of elemental sulfur in two distinct stages wherein oxygen-containing gas in a quantity which is initially less than that stoichiometrically required for total combustion of the sulfur to sulfur dioxide and the sulfur-dioxide gases and residual elemental sulfur are thereupon passed through a heat exchanger and subjected to an afterburning with additional quantities of oxygen-containing gas. 70% to 95% of the total oxygen required for combustion of sulfur is supplied in the initial or combustion stage and the remainder (i.e. 30 to 5%) is supplied in the afterburning stage.
