Abstract
A dual phase fuel vaporizing combustor, and method for burning, in an annular vaporizing combustor, high viscosity, high carbon/hydrogen ratio hydrocarbon fuels, including such as residual fuels, low grade synfuels and coal-oil slurries. A dual phase vaporizer tube receives alternating introductions of a fuel air mixture of high fuel content, and then a hot air or low fuel content mixture, to alternately initially discharge from the tube a vapor stream of combined air and partially vaporized fuel, the initial vapor stream impinging onto a hot surface where more volatile portions of fuel will vaporize and burn, while less volatile heavier fuel components will form a hot carbon deposit on the surface; and alternately and sequentially discharge from the tube a hot, highly oxidizing stream with little or no fuel and impinge the sequential stream onto the carbon deposit on the hot surface and thereby promote substantial burning of the carbon.
