<p>Air is supplied along a pipeline 8 to an apparatus 2 for separating an oxygen-enriched gas stream from the air by vacuum swing adsorption. The oxygen-enriched gas stream is supplied to a burner 12 which fires into a furnace 14. A hot gas stream leaves the furnace 14 through an outlet 20. Steam is raised from the hot gas in a waste heat boiler 22. Steam so raised flows through one or more of the eductors 24, 26, 28, and 30 to draw through a pipeline 6 the vacuum necessary for the operation of the vacuum swing adsorption apparatus. <IMAGE></p> |
