Forced circulation steam generator - has injector supplied from tapping between economiser and evaporator and temperature controlled regulator controlling flow to evaporator

摘要

The forced-circulation steam generato is particularly of the pressure variation type, having in series a water feed, an economiser, a water separator and a superheater. First and second temperature measuring devices are mounted respectively in a first part of the superheater and at the end of it, an injector being situated between them. A first injector is connected to an injection pipe tapped off between the economiser and the evaporator. A regulator controls the flow of water to the evaporator in response to the signal from the first temperature measuring device representing the actual value, and to a signal which is a function of the load and represents the desired value.
