INJECTION MEMBER FOR COMBUSTION REACTION FURNACE, PARTICULARLY, STEAM GENERATOR

摘要

The injection element comprises a fuel inlet, an oxidant inlet, a mixing chamber for fuel and oxidant, and an ignition device for a mixture of fuel and oxidant. To ensure optimum mixing of the reaction components and efficient ignition even in the case of small reactors, the fuel inlet opens into an ignition chamber having a widened flow cross-section, the ignition chamber has an outlet having a cross-section smaller than the flow cross-section of the ignition chamber, the outlet of the ignition chamber and the oxidant inlet open into the mixing chamber, an ignition oxidant inlet opens into the ignition chamber and the ignition device is disposed in the ignition chamber immediately upstream of its outlet.
