<p>A sulfur-burning combustor generates hot sulfur dioxide that is mixed wit h dry air or recycled sulfur dioxide to form a mixed working gas for a gas t urbine to ensure that the temperature of the working gases is kept below the maximum allowable temperature of the blades of the turbine. The turbine dri ves an oxygen compressor which supplies oxygen to a bubbling chamber which a lso receives S8 to produce sulfur vapor (predominantly diatomic sulfur) for combustion. By using stoichiometric quantities, the end product, sulfur diox ide, is delivered in requisite quantities to a sulfuric acid plant without a ny harmful emissions. Useful amounts of electrical power can thus be generat ed by the gas turbine (topping device) as well as the downstream steam turbi ne by harnessing the enormous amount of waste heat involved in the manufactu re of sulfuric acid.</p> |
