ABSTRACT:
In a combined cycle power plant, gas turbine exhaust gas is passed through a heat recovery steam generator (HRSG) wherein it may be reheated upstream from a boiler tube section prior to passing through the boiler tube section in a non-contact heat exchange relation with a feedwater supply to produce steam for driving a steam turbine. A plurality of air-atomized, liquid fuel wall burners are utilized, each in combination with a "vee"-shaped flameholder to heat the gas turbine exhaust gas. Each wall burner may be disposed in a recessed opening in the HRSG duct wall and each wall burner has a nozzle portion which may be directed upstream relative to the exhaust gas flow. Each flameholder is approximately parallel to its respective wall burner nozzle axis having one end fixed to the duct wall, upstream from the nozzle axis, and a free end disposed within the HRSG duct.
