Abstract:
An oxygen fueled combustion system comprising:a furnace having at least one burner, and configured to substantially prevent the introduction of air; an oxygen supply for supplying oxygen having a purity of at least about 85 percent; a carbon based fuel supply for supplying a carbon based fuel; means for feeding the oxygen and the carbon based fuel into the furnace in a stoichiometric proportion to one another; means for limiting an excess of either the oxygen or the carbon based fuel to less than 5 percent over the stoichiometic proportion; and means for controlling the combustion of the carbon based fuel to produce a flame temperature in excess of about 4500Â° F., and to produce an exhaust gas stream from the furnace having a temperature of not more than about 1100Â° F.
