ABSTRACT:
A system for regulating the liquid level (20) in a vapor generator (10), in which the incoming flow of feed liquid (54) is regulated (48) in response to the difference between the measured liquid level (76) and a reference level (80), the difference between the exiting vapor mass flow rate (64) and the incoming liquid mass flow rate (56), and a function of the measured incoming liquid temperature (92). The temperature function produces a gain value (98), which increases in response to decreasing incoming liquid temperature.
