Boiler Control for Fossil-Fired Utility Boilers

2013-2-19  Coordination between the Boiler Controls and the Turbine Controls is critical for maximizing stability and unit response. The Master Control section, often referred to as the Front End, consists of the Unit Master, Turbine Master, and Boiler Master subgroups. These three subgroups coordinate the actions of the boiler and turbine. The Unit Master can operate in one of four

US4445180A - Plant unit master control for fossil fired ...

An electric power plant, including a fossil fired boiler and a steam turbine, is operated by a control system including a plant unit master. The control system includes a boiler control for determining the inputs of fuel, air and water, and a turbine control for determining the position of the throttle valves introducing steam from the boiler to the turbine.
