Oxygen mixer for oxygen combustion boiler
In an oxygen mixer for an oxygen combustion boiler, circulating exhaust gas heated in a rotary preheater is mixed with oxygen. Resultant mixed gas is guided to a boiler furnace through a combustion gas duct having bends. At the bend closest to the rotary preheater in the combustion gas duct, an oxygen injection nozzle is arranged to have a plurality of injection ports for injection of oxygen into circulating exhaust gas.
