Gas-solids separation units and methods for the manufacture thereof

Abstract

Embodiments of a gas-solids separation unit and embodiments of a method for manufacturing a separation unit are provided. In one embodiment, the separation unit includes a cyclonic separator and a vessel having a flue gas chamber, a clean gas chamber, and an entrained solids chamber between the flue gas chamber and the clean gas chamber. The cyclonic separator includes, in turn, a cyclone barrel extending from the flue gas chamber toward the clean gas chamber, a swirl vane positioned across the cyclone barrel, a gas outlet tube fluidly coupling the cyclone barrel to the clean gas chamber, and a first check valve opening formed through the barrel sidewall upstream of the gas outlet tube. The check valve opening fluidly couples the cyclone barrel to the entrained solids chamber to permit the centrifugal separation of the particulate matter from the gas stream during operation of the gas-solids separation unit.
