Automatic Start-Up and Operation of Power Generating Plants With a Combined Gas-Steam Cycle

This paper concerns two power stations using a combined thermal cycle where the heat of the exhaust gases is recovered in a boiler which delivers superheated steam to a steam turbine. After a description of the start-up process, it deals with a few typical problems which had to be solved in working out the automatic and semi-automatic control systems. It also describes auxiliary elements such as the control panel and the supervisory system. The choice between automatic and semi-automatic plants is discussed.
