ABSTRACT:
A method is provided for reducing the sulfur content of exhaust (flue) gas from a combustion installation manufacturing process, or chemical process comprising the step of injecting dry powder alkali hydrate sorbent directly into intermediate temperature (800.degree.-1200.degree. F.) combustion/process gases. The alkali hydrate sorbent reacts rapidly with the sulfur-containing gases in this temperature regime to produce primarily alkali sulfites. The unreacted portion of the sorbent largely remains in the form of an alkali hydrate and may react further with residual sulfur, especially in the presence of water, at lower temperatures. A novel combustion chamber is also provided having an injection means for injecting alkali hydrate sorbent into a combustion volume where the temperature is in the range of 800.degree.-1200.degree. F., to cause a predetermined reaction of the alkali hydrate sorbent with SO.sub.2 and the combustion gases to produce primarily alkali sulfites with the unreacted sorbent remaining substantially as alkali hydroxide.
