Abstract
An anti-pollution system for industrial smoke stacks has a source of live steam feeding steam to a nozzle centered in the upper part of the stacks and several concentrically steam cooling towers of progressively smaller diameter. Each chamber opens into the other and has a drain for conveying water laden with unburned particles and soot to filters at the bottom of the stacks.
