摘要： A method for avoiding the spontaneous ignition of combustible dusts in process off-gases, wherein during the process the dusts are retained, without adversely affecting the process parameters, at least one sintered filter element which is arranged in a pressure vessel and is able to withstand temperatures of up to at least 250° C. and after the process has ended the dusts are inerted by blasting oxygen-containing gas back into the pressure vessel, and to a device for carrying out the method.
