ISA77.42, Feedwater Controls

Scope

The scope of this standard is to address the major steam temperature control subsystems in boilers with steaming capacities for 200,000 lb/hr (25 kg/s) or greater. These subsystems include, but are not limited to, superheat temperature control, reheat temperature control. Specifically excluded from consideration are turbine bypass control, motor control logic, combustion control, sootblower control, as well as all controls associated with fluidized bed and stoker fired furnace combustion units.

Purpose

The purpose of this standard is to establish the minimum requirements for the functional design specifications of steam temperature control systems for drum-type fossil-fueled power plant boilers.
