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.??
