on the first device to feed water to a steam generator flow have a single journey

摘要

The forced circulation steam generator is provided with a means for measuring the difference in pressure between two levels in the water separator in order to measure the water level in the separator. The water feed rate to the evaporator is controlled in dependence on the measured pressure difference in the separator when the separator contains water and in dependence on another variable, such as the temperature at the outlet of a superheater, when the separator is dry.
