ANSI/ISA-77.42.01-1999 Fossil Fuel Power Plant Feedwater Control System
– Drum-Type
General reference,
softbound, 34pp.
$65.00
Establishes minimum criteria for the control of levels, pressures, and flow for the safe and reliable operation of drum-type feedwater systems in fossil power plants. Aids in the development of design specifications covering the measurement and control of feedwater systems. The following requirements are defined for minimum system design:
- process measurement requirements;
- control and logic requirements;
- final control device requirements;
- system reliability and availability;
- alarm requirements; and
- operator interface.
The safe physical containment of the feedwater shall be in accordance with applicable piping codes and standards and is beyond the scope of this standard.
Scope:
The standard is intended to assist in the development of design specifications
covering the measurement and control of feedwater systems in boilers with
steaming capacities of 200,000 lb/h (25 kg/s) or greater. The safe physical
containment of the feedwater shall be in accordance with applicable piping
codes and standards and is beyond the scope of this standard.
Purpose:
The purpose of this standard is to establish the minimum criteria for
the control of levels, pressures, and flow for the safe and reliable operation
of drum-type feedwater systems in fossil power plants.
