Abstract:
1. A method of generating a hot stream of carbon monoxide gas comprised of Supplying a low-value, calcined fuel coke to a first hopper, Feeding the fuel coke through an inlet conduit from the first hopper into a combustor vessel having and upper end with a start-up burner attached and a lower end attached to a debris bin, Igniting the start-up burner attached to an oxidizer chamber attached to the combustor and flowing combustion gases from the burner through the oxidizer and into the upper end of the combustor vessel, Contacting the calcined fuel coke in the upper end of the combustor with the hot gases from the oxidizer such that the fuel coke is heated and ignited, Combusting the fuel coke until all of the oxygen is consumed in the combustor, Feeding additional fuel coke from the first hopper to the combustor to replace combusted coke in the combustor, Removing uncombusted fuel coke and solid impurities from the debris bin, and Extracting hot gases from the lower end of the combustion vessel above where uncombusted fuel coke and solid impurities and ash are removed to the debris bin.
