Compact heat exchanger with high intensity burner

Abstract

Abstract A high intensity burner for burning a carbonaceous fuel in an oxygen containing atmosphere has one or more ports through which the fuel emerges and adjacent which complete combustion of the fuel occurs within a limited combustion region at a temperature above the dissociation temperature of CO2. A heat exchanger, which is maintained at a temperature below the recombination temperature of CO and O2, is located outside the limits of said combustion region but sufficiently close to the burner ports so that, at the normal operating velocity of the burned gases these gases would reach the heat exchanger before the temperature of the gases had dropped below the dissociation temperature and into the recombination temperature range, except for the fact that a screen is located between the limits of the combustion region and the heat exchanger, and is heated by the gases, thereby extracting heat from the gases, to a temperature at which it radiates energy, thus reducing the temperature of such gases into the recombination temperature range before they reach the heat exchanger.
