Abstract
Abstract The flue gases, which are generated in a combustion chamber through combustion of solid fuels, particularly under increased pressure, are cleared of dust in a dust removal device which consists of a plurality of tubular ceramic filter elements open at one side. These filter elements are suspended in a plate, which represents the ceiling of the combustion chamber.
