About

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 drum-type 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 firing rate demand development, throttle/header pressure control, and unit megawatt/steam flow control as applicable.

This Standard will address two types of process applications:
a) a single boiler supplying a single turbine, typical of an electric utility power plant; and
b) a single boiler or multiple boilers supplying a common distribution header, typical of an industrial power plant.

Specifically excluded from consideration are:
a) dispatch control;
b) turbine/generator control (other than turbine demand);
c) combustion controls (covered separately by ANSI/ISA–77.41.01, Fossil Fuel Power Plant Boiler Combustion Controls);
d) steam distribution control systems;
e) economic loading of boilers; and
f) fluidized bed boilers.
