Abstract:
A method of cleaning flue gases from gaseous pollutants formed during combustion of oil during at least one of start-up of a boiler and operational disturbances in the boiler, wherein the boiler is for combustion of fuel including one of fossil fuel, coal, biomass fuel and waste, the method comprising:conducting flue gases from the boiler through a flue duct to a barrier filter for separation of particulate pollutants; introducing finely-dispersed particles into and mixing with the flue gases in the flue duct in at least one of upstream of and in the barrier filter; and separating the finely-dispersed particles in the barrier filter while forming a dust cake; whereby condensed gaseous pollutants and droplets are taken up on the surface of the finely-dispersed particles in the flue gases and in the dust cake.
