ABSTRACT:
The forced-flow steam generator is provided with a control means for controlling the amount of water fed to the evaporator. The control means includes a controller which receives a load-dependent signal and an actual value signal from a temperature measuring means. The steam generator includes an injection line which communicates at a point downstream of the temperature measuring means. The controller may be connected directly to a valve in the injection line in order to regulate the amount of water which is bypassed around the evaporator or may be connected directly to the feedwater supply to maintain a constant flow to the evaporator during injection of water.
