<p>A method for reducing the risk for coatings and cloggings of heat absorbing surfaces present above the black liquor sprayers in a recovery boiler, whereby the oxygen concentration in the recovery boiler is increased on at least one level above said black liquor sprayers, for the purpose of increasing the combustion speed for pyrolytic gases and thereby reducing the gas temperature prior to its entrance into the superheater area.</p> |
