MAIN BURNER, METHOD AND APPARATUS

摘要

A method and apparatus for use with a main burner of a gas turbine is disclosed. A rich fuel air mixture is catalytically oxidized with the resulting reacted mixture (48) being made lean by having additional air (46) added thereto. The resulting lean mixture (49) is then combusted in the presence of the main mixture (72) that is also lean thereby supporting combustion of the main mixture (72).
