GESTRA Modulating Level Control

Modulating Systems (control valves, frequency-controlled pumps)

With modulating control, one thinks first of the economical operation, higher steam quality and the capability of adapting to difficult situations regarding the controlled systems, e.g. those caused by strong fluctuations or sudden changes in steam consumption, as is the case for process-related reasons in the industries.

The greater operational economy of the boiler and the higher steam quality are naturally an aspect of the controlled, demand-oriented make-up of the boiler water. On the one hand, this mode ensures con tinuous burner operation and, on the other, the boiler water level is not elevated as high as with the two-position control, which then reduces the danger of carry-over appreciably.
