Abstract
A combustoris operative to effect therewith the combustion of fossil fuel' in order to thereby both heat to a working fluidand generate a flue gas. An air preheaterreceives the flue gasgenerated in the combustor. A blowercauses airto flow to the air preheaterwhen operating in an air fired mode, and causes both Oand recycled flue gas′ to flow when operating in the Ofiring mode. The air preheateris operative to transfer heat from the flue gasreceived thereby to the airthat is received when operating in an air fired mode or to both the received Oand the recycled flue gas′ that is received when operating in the Ofiring mode in order to thereby effect a preheating of the airor of both the Oand recycled flue gas,′ depending upon the specific nature of the mode of operation thereof, and to thereby effect therewith a cooling of the flue gas received thereby. The preheated airor both the preheated Oand the recycled flue gas′, depending upon the specific nature of the mode of operation, is caused to flow from the air preheaterto the combustorin order to thereby effect therewith a fluidization of the fossil fuel
