Industrial Boiler Water Chemistry & Control
Industrial boiler water chemistry is the precise management of feedwater quality, oxygen scavenging, alkalinity, and Total Dissolved Solids (TDS) to control scale formation, corrosion, steam carryover and overall steam-system performance. Effective chemistry control helps protect boiler equipment, maintain steam purity and support efficient steam generation.
1. Feedwater Quality & Pre-Treatment Control
Protecting steam-generation infrastructure begins before water enters the boiler vessel. Effective pre-treatment and feedwater conditioning help control the primary drivers of scale formation, corrosion and tube damage.

Feedwater pH Control: Feedwater pH is closely controlled to minimise corrosion of iron and steel components within the system. Appropriate control ranges depend on boiler design, operating pressure, feedwater characteristics and the overall treatment program.
Dissolved Oxygen Removal: Dissolved oxygen can cause aggressive localised pitting in boiler headers, steam drums and condensate piping. Integra uses mechanical deaeration combined with specialised oxygen scavengers, where appropriate, to help control dissolved oxygen and protect critical steam-generation infrastructure.
Softened Water Make-Up: Feedwater pre-treatment is used to control hardness-forming calcium and magnesium before water enters the boiler. Integra assesses softening performance and feedwater quality to help prevent hardness breakthrough and the formation of scale on heat-transfer surfaces.
2. Internal Boiler Water Chemistry & Parameter Precision
As steam is generated, dissolved impurities become increasingly concentrated within the boiler water. Maintaining appropriate internal chemistry helps control scale, corrosion, foaming and carryover while protecting boiler assets and supporting steam purity.
Caustic Alkalinity (Hydroxide Alkalinity): Appropriate alkalinity control helps maintain protective conditions within the boiler and supports effective control of scale-forming deposits. Treatment requirements depend on boiler design, operating conditions, feedwater quality and the overall chemical treatment program.
Total Dissolved Solids (TDS) & Blowdown Control: As dissolved solids concentrate in boiler water, excessive TDS can contribute to foaming, wet steam and carryover into downstream steam equipment. Integra assesses TDS, cycles of concentration and blowdown requirements to establish appropriate control parameters for the individual boiler, with automated blowdown used where appropriate to improve consistency and reduce avoidable water and energy losses.
3. Automated Control & Turnkey Support
Reliable boiler water treatment depends on accurate dosing, consistent monitoring and correctly calibrated control equipment. Integra Water provides automated chemical dosing systems, continuous monitoring controllers and scheduled multi-point calibration to help maintain consistent treatment control and support efficient, reliable steam generation.
