This report describes the formation and their prevention of acid smuts at oil-fired industrial boilers. Results obtained from the field tests were as follows.<BR>1) The acid smuts were mainly formed in the stack and falled out within the limits of 400m from the stack in conditions of light wind.<BR>2) Full load condition and load up period were critical from the point of view of smuts emission, which increased with increasing excess air.<BR>3) Three methods of prevention against acid smuts emission tried were.<BR>a) to retain minimum excess oxygen under 1.0 percent in order, to decrease the acid dew point below flue gas temperatures.<BR>b) to neutralize SO3 by mean of NH3 injection of over 0.04 percent by weight of fuel oil.<BR>c) most steam-power plants in Japan have been operated eliminating completely not only acid smuts but dust in flue gas.
