An oxygen fueled combustion system includes a furnace having at least one
burner, an oxygen supply for supplying oxygen having a predetermined
purity, and a carbon based fuel supply for supplying a carbon based fuel.
The oxygen and the carbon based fuel are fed into the furnace in a
stoichiometric proportion to one another to limit an excess of either the
oxygen or the carbon based fuel to less than 5 percent over the
stoichiometric proportion. The combustion of the carbon based fuel
provides a flame temperature in excess of 4500.degree. F. The exhaust gas
stream from the furnace has substantially zero nitrogen-containing
combustion produced gaseous compounds from the oxidizing agent and reduced
green-house gases. Substantially less carbon based fuel is required than
conventional combustion systems without a loss of energy output.
