Abstract
A process and apparatus for the production of reformed gases. Natural gas and/or liquid hydrocarbons and oxygen are combusted in a first stage to produce carbon dioxide and water. The products of combustion are conveyed to a second stage. Reforming gas or atomized liquid hydrocarbons and oxygen are injected into the second stage and mixed with the products of combustion to react with the carbon dioxide and water to produce carbon monoxide and hydrogen. The process and apparatus are particularly adapted for use in supplementing the reform gases produced in a Direct Reduced Iron plant wherein iron ore is reduced to iron inside a shaft furnace. The process and apparatus may also be used to provide heated enrichment natural gas or liquid hydrocarbons for use as a source of carbon in the shaft furnace to provide for carburization of the iron. Additionally, the process and apparatus may be used as a process control device for controlling the temperature of the reformed gases flowing to the shaft furnace.
