Abstract
Air is supplied along a pipeline to an apparatus for separating an oxygen-enriched gas stream from the air by vacuum swing adsorption. The oxygen-enriched gas stream is supplied to a burner which fires into a furnace. A hot gas stream leaves the furnace through an outlet. Steam is raised from the hot gas in a waste heat boiler. Steam so raised flows through one or more of the eductors to draw through a pipeline the vacuum necessary for the operation of the vacuum swing adsorption apparatus.
