Abstract
A pebble-bed evaporator and superheater assembly includes a tubular pressure shell with internal baffles, the latter including a plurality of apertures therein for passage of gas therethrough. Contained within the shell are heater elements and pebble elements which store heat and transfer the same to liquified gas which is vaporized and flows through the shell whereby the gas supplied to the shell and is heated to a predetermined elevated temperature above its input temperature. The heated gas output of the shell flows to a mixer unit connected to the shell and the mixed gas flows out of the mixer. Connected to the mixer is a supply of liquified gas to cool the high temperature gas entering the mixer from the shell such that the temperature of the gas exiting the mixer is below the temperature of the heated gas exiting the shell. In this way the temperature of the gas exiting the mixer is controlled to the desired level.
