Power plant with efficient emission control for obtaining high turbine inlet temperature
A method is described for burning fuel in a combustor comprising the steps of: combusting a carbonaceous sulfur-bearing fuel and thereby producing a gas with contaminants; and conveying the gas to a fluidized bed reactor including circulating particulate matter and an operating temperature of at least 1,500 F so that the gas reacts with the circulating particulate matter to reduce the contaminants in the gas; injecting a gaseous reactant into the fluidized bed reactor to further reduce the contaminants in the gas; positioning heat exchangers within the fluidized bed of the fluidized bed reactor for heating a pressurized air stream within the heat exchangers; and conveying the pressurized air stream from the heat exchangers into a refractory heat exchanger closely coupled to the combustor.
