Technical details and manufacturing context for Feedwater Treatment System

Definition

The Feedwater Treatment System is a component within an industrial steam generation system for process heating. Its function is to prepare and condition water before it enters the boiler. The system removes dissolved solids, gases, and suspended particles to ensure efficient heat transfer, protect boiler internals from damage, and produce high-quality steam for industrial processes. The treatment process typically includes filtration, softening (ion exchange), deaeration, and chemical dosing, depending on raw water quality and boiler operating pressure. The system is available with rated capacities from 10 to 100 t/h, operating pressures from 1.0 to 1.6 MPa, and operating temperatures from 20 to 80°C. Filtration precision ranges from 5 to 50 μm (ISO 16889), and the pH range is 8.5 to 9.5. Electrical supply is three-phase, 50 Hz, 380 V ±10% (IEC 60038), with power consumption from 5 to 50 kW. Ingress protection is IP54 to IP65 (IEC 60529). Materials include stainless steel (grades 304 to 316L per ASTM A240), carbon steel, PVC/plastic for certain tanks and piping, and ion exchange resin. The system is skid-mounted and forklift accessible, with weights from 500 to 5000 kg. These values are reference ranges; verify model-specific specifications with the manufacturer or supplier.

Working Principle

Water is treated through a sequence of processes that may include filtration to remove suspended particles, softening via ion exchange to reduce hardness, deaeration to remove dissolved oxygen and carbon dioxide, and chemical dosing with oxygen scavengers and pH adjusters. The specific treatment train depends on raw water quality and boiler operating pressure. The system ensures that feedwater meets required quality standards to prevent scaling, corrosion, and carryover in the boiler.
