A steam-pressured eliminator for use on top of a tall, industrial-type, brick or metal smoke stack to reduce their pollution of the atmosphere. This eliminator is operated by pressurized steam directed so as to intercept the flow of smoke tending to leave the stack and releases to the atmosphere only cleansed smoke and steam. The steam condensate with the smoke particles are drained off from the stack attached vessel. The smoke eliminator is such that the eliminator can be assembled to the stack as a unit, as by the use of a helicopter, and in some forms the steam generator is made a part of the unit so as to be inserted in the stack suspended from the top thereof and be heated by the hot gases of the stack itself. Preferably when the stacks are of brick the attachment is made to top and exterior surfaces thereof. When the stacks are of metal the unit can be wedged into the top opening of the stack and the unit vessel being tapered, can be fitted to various diameter sized stacks. A collapsible steam generator of tapered sleeve parts is provided to compact the unit at times it is being handled by the helicopter and make it more easy to insert or install in the stack. A rain collection vessel is provided in one form into which a supply of water can be poured from the helicopter hovering thereover when not kept filled by rain water.
