The document gives guidance on the proper design of the control circuits for steam generators in fossil fired power stations. It describes appropriate circuitry for the control circuits, and a further part deals with the measuring instruments and actuators needed to realise the control unit. It describes measures serving to maintain the negative pressure in the combustion chamber of fossil fired steam generators.
