Abstract
There is provided method and apparatus for creating a longitudinally disposed, sharp puff of gas, useful for puffback renewal of gas-entry faces of a panel-bed gas filter or a panel-bed gas-powder contactor. Perforations are disposed along the wall of a tank in a path generally parallel to the tank's axis. Stoppers are provided for stoppering the perforations. With the perforations so stoppered, a gas is introduced at high pressure into the tank. Thereafter, quickly unstoppering the perforations releases the gas from the tank in form of a longitudinally disposed, sharp puff of gas moving in a direction perpendicular to the tank's axis. If the tank is placed vertically alongside or within a space receiving gas from a panel bed, the sharp puff can effectively puffback the panel bed.
