Abstract
This invention relates to a method for the production of gases free from particulate contaminants, for use in driving gas turbines without causing fouling or corrosion of the blading. The method comprises feeding a gas contaminated with particulate material, for instance produced by the combustion or gasification of coal, and a tackifying material, such as a crackable hydrocarbon or an inorganic compound, to a collection medium, preferably a fluidized particle bed, maintained at a temperature whereat the tackifying material becomes sticky and is deposited on the collection medium. The contaminants are removed by becoming stuck thereon.
