HIGH EFFICIENCY STEAM EJECTOR FOR DESALINATION APPLICATIONS

摘要

A high efficiency ejector (100) for use in desalination applications includes a mixing duct (32), a boiler, a primary high pressure steam duct (12) connected to a plurality of inner supersonic nozzles (22) and a plurality of outer supersonic nozzles. The inner nozzles and the outer nozzles have axes that are canted radially with respect to each other, in an asymmetric arrangement or in a 2-dimensional geometric arrangement. The inner nozzles and the outer nozzles each communicates with the mixing duct. A secondary duct communicates with steam exiting the inner nozzles and the outer nozzles upstream of the mixing duct.
