66. Regarding the low pressure evaporator steam control orifice in the live steam supply line, the steam at the outlet of the orifice if not properly conditioned will be developed as __________.

Throttling steam through a control orifice reduces pressure without significant heat loss, resulting in superheated steam unless desuperheating occurs. The orifice itself does not desuperheat; it increases superheat. Therefore, without proper conditioning, the outlet steam will be superheated.
