Device for stabilizing dilute combustion in a cold-wall combustion chamber

Abstract

A device for stabilizing dilute combustion for use in a cold-walls type combustion chamber comprises a burner. The burner comprises at least one oxidant inlet and at least one fuel inlet. The oxidant and fuel inlets opening separately into the chamber at a distance suitable for establishing combustion which is highly diluted by internal re-circulations of combustion products toward a burner zone. The device comprises a heating element configured to heat, during steady operating conditions, the combustion products to sustain self-ignition conditions. The heating element is positioned in a dilution zone and surrounds a set of oxidant and fuel jets.
