Figures 6-5 and 6-6 illustrate two-stage ejector installations with barometric and surface t) pe inter-after condensers respectively. The discharge of the steam non-condensables from the second stage jet of Figure 6-5 is exhausted to the atmosphere, while in Figure 6-6 the steam is condensed in the aftercondenser and, essentially, only non-condensables leave the ent of the aftercondenser. Figure 6-7A indicates a diagram of a three-stage barometric type installation.
