Fraas, A P

Research and development experience with advanced energy conversion systems that might be employed with fossil fuels is reviewed for the purpose of appraising the development prospects of each system. The thermal efficiency of power cycles using: steam turbines; gas turbines; combined gas turbine-steam turbines; closed-cycle gas turbines; alkali metal vapor topping cycles; MHD generation; and aqueous fuel cells are compared. It is concluded that, for fossil fuel plants, the most promising innovation having good prospects for a near-term payoff in reduced costs and some increase in thermal efficiency is the fluidized-bed coal combustion system heating water or air blowing through a tube matrix in the bed coupled to a steam or a gas turbine.
