Details
The purpose of this document is to establish the minimum requirements for the functional design specifications of unit/plant demand development for control systems for fossil-fueled power plant boilers.
The scope of this standard is to address the unit/plant demand development subsystem for boilers with steaming capacities of 200,000 lbs/hr (25 kg/s) or greater. This subsystem includes generation demand, boiler demand development, turbine demand development, throttle/header pressure control, and unit megawatt/steam flow control as applicable.
This standard will address two types of process applications:
a single boiler supplying a single turbine, typical of an electric utility power plant, and
a single boiler or multiple boilers supplying a common distribution header, typical of an industrial power plant.
Specifically excluded from consideration are:
dispatch control,
turbine/generator control (other than turbine demand),
feedwater controls
steam temperature controls (covered separately by ANSI/ISA-77.44.01, Fossil Fuel Power Plant – Steam Temperature Controls),
combustion controls (covered separately by ANSI/ISA-77.41.01, Fossil Fuel Power Plant Boiler Combustion Controls),
steam distribution control systems,
economic loading of boilers, and
fluidized bed boilers.
