Resumo
With increasing energy conservatism and pending CO2 legislation, steelmakers are striving towards fuel savings, energy efficiency improvements and the use of alternate fuels. Oxy-fuel technologies offer an economically feasible solution to meet these objectives. Compared to air-fired combustion systems, oxy-fuel technology can deliver up to 80% reduction in flue gas volumes, up to 50% fuel savings, up to 90% reduction in NOx emissions and the ability to substitute fuels. The specific benefits for each case are a function of several variables that are discussed in the paper. In addition, the paper describes how Praxair's Dilute Oxygen Combustion (DOC) technology overcomes all the classical concerns of oxy-fuel systems to offer an ideal oxy-fuel solution.
