摘要： A method for reducing nitrogen oxides of a recovery boiler, and a recovery boiler, where the furnace of the recovery boiler is supplied with primary air from primary air nozzles, black liquor from liquor nozzles, secondary air from secondary air nozzles above the primary air nozzles but still below the liquor nozzles, tertiary air from tertiary air nozzles above the liquor nozzles, and quaternary air from quaternary air nozzles above the tertiary air nozzles. Black liquor is supplied to the furnace from first liquor nozzles and second liquor nozzles, which liquor nozzles are arranged substantially on the same level with respect to the height of the furnace, and the droplet size of liquor fed from the second liquor nozzles is substantially smaller than the droplet size of liquor fed from the first liquor nozzles.

摘要： A method and an arrangement for supplying air to a fluidized bed boiler are disclosed. In the method, the air is supplied from all comers of the fluidized bed boiler substantially parallel to two opposite walls and from the middle of said walls toward the center of the fluidized bed boiler whereby the air flows cause the formation of four vortexes in the fluidized bed boiler. The arrangement comprises nozzles that blow air jets towards each other parallel to the opposite walls of the fluidized bed boiler and nozzles in the middle of the walls arranged to blow air toward the center of the fluidized bed boiler.

摘要： A method and an arrangement for supplying air to a recovery boiler. In the method, the air is supplied to the recovery boiler at at least one air supply level so that four vortices are formed therein, the vortices spinning, in pairs, in opposite directions to one another so that any two adjacent vortices always spin in opposite directions to one another. The arrangement comprises nozzles that are arranged to blow air so that four vortices are formed in the recovery boiler, any two adjacent vortices always spinning in opposite directions to one another.
