Abstract
Filter assemblies, such as ceramic or super alloy filter tubes, for combustible gases laden with particles, are safely cleaned by providing a back pressure pulse of a clean combustible gas. The clean combustible gas, such as methane, ethane, propane, or butane, and may either be stored in an accumulator or tank as gas, or may be stored in liquid form and flashed into a gas before use. The pulsing gas may pass through a venturi, intermittent or periodic control of the valve to supply the back pressure gas through the venturi being provided. The cleaned combustible gas mixes with the clean combustible gas and passes through the filter assembly to a use station, such as a combustor where the gases are burned.
