摘要： An apparatus and method for producing sulfur comprises a vessel containing a plurality of spaced-apart channels each having an upstream end communicating with an upstream manifold and a downstream end communicating with a downstream manifold. Each channel comprises a single, continuous, uninterrupted conversion stage terminating at the downstream channel end. A first mixture, of SO2 and air from the sulfur burner, is introduced into the upstream manifold and flows as a stream through each of the channels where the stream is cooled and the SO2 is converted in the conversion stage to SO3 to produce, at the downstream channel end, a second mixture consisting essentially of SO3 and air. The first mixture is not cooled between the sulfur burner and the converter. The stream flowing through the conversion stage is maintained at a temperature which sustains conversion of SO2 to SO3, without diluting the stream with a cooling fluid or diverting the stream outside the channel contained in the converter vessel.

摘要： A method for conditioning flue gas to improve the removal of fly ash by an electrostatic precipitator employs a relatively high concentration (4-71/2%) of SO.sub.3 conditioning agent. The SO.sub.3 is formed by combusting sulfur and excess air in a sulfur burner to produce a mixture of air and SO.sub.2 and converting the SO.sub.2 to SO.sub.3 in a catalytic converter. The ratio of air to sulfur is maintained constant over a wide range of SO.sub.3 production rates, and the air is unheated during most production rates. The mixture of air and SO.sub.2 from the sulfur burner is cooled without increasing the volume of the gaseous mixture.
