DEVICE FOR STABILIZING THE DILUTE COMBUSTION IN A COOLED-WALLS COMBUSTION CHAMBER

摘要

The device for stabilizing dilute combustion which is intended to be used in a combustion chamber (245) said to be of the cooled-walls type, equipped with a burner comprising at least one oxidant inlet (205) and at least one fuel inlet (210), the oxidant and fuel inlets opening separately into the chamber at a distance suited to the setting-up of combustion (240) which is highly diluted by internal recirculations (220) of the products of combustion towards the burner region, which device comprises a heating element (215) designed to reheat, during steady operating conditions, the products of combustion in order to sustain self-ignition conditions, said heating element being positioned in the dilutions region and surrounding the set of oxidant and fuel jets (295).
