Anti-Foam Solutions for Industrial Boilers

Eliminating Carry Over Problems for Enhanced System Performance

Carryover in industrial boilers isn’t merely an inconvenience—it’s a significant operational impact that can compromise system integrity, reduce efficiency, and lead to costly downtime. At ETI, we have expertise to identify and problem-solve the cause of steam caryover. Causes may include chemistry, design, mechanical and/or operating factors.

Understanding Foam Formation in Boiler Systems

Foam in boiler systems occurs is the result of various chemistry factors, such as, elevated dissolved solids, oils, organic materials, and/or treatment chemicals reach critical concentrations and reduce surface tension at the steam-water interface. This seemingly minor issue can cascade into serious operational problems:

  • Carryover Contamination: Foam facilitates the transport of boiler water impurities into steam lines, contaminating downstream equipment

  • Reduced Heat Transfer: Foam layers act as insulators, decreasing thermal efficiency and increasing fuel consumption

  • False Water Level Readings: Foam can trigger inaccurate level gauge readings, risking dry-firing or flooding conditions

  • Mechanical Damage: Impurities carried by foam can deposit on turbine blades and other critical components

  • Increased Blowdown Requirements: Attempting to control foam through additional blowdown wastes water, chemicals, and energy

Even well-maintained boiler systems can experience foam formation during load swings, feedwater quality fluctuations, or after maintenance activities. ETI’s anti-foam solution provides the operational stability your system demands in all conditions.

The ETI Advantage in Foam Control Technology

Our advanced anti-foam product and custom-blended formulations represent the culmination of decades of research specifically focused on high-pressure, high-temperature industrial environments.

Thermal Stability Under Extreme Conditions

Standard defoamers can break down under boiler operating conditions, providing only temporary relief. ETI’s anti-foam technology utilizes thermally stable compounds engineered to maintain effectiveness even under extreme pressure and temperature conditions, providing consistent foam suppression throughout your operational cycle.

Compatibility with Comprehensive Treatment Programs

Our anti-foam solutions are designed to work synergistically with your existing water treatment chemistry, including:

  • Oxygen scavengers

  • Scale inhibitors

  • Corrosion inhibitors

  • Alkalinity builders

This compatibility ensures foam control without compromising your overall water treatment program effectiveness.

Minimal Impact on Steam Purity

ETI’s formulations effectively suppress foam thus maintaining steam purity standards including compliance with FDA, USDA, Kosher and Organic certified operations. Our products are engineered to:

  • Minimize chemical carryover

  • Preserve steam quality

  • Protect downstream equipment

  • Meet stringent process requirements

Applications Across Boiler Types

Our anti-foam solutions are precisely formulated for specific boiler applications:

Fire-Tube Boilers Provides foam control while protecting tube sheets and fire-side surfaces from temperature excursions caused by foam-related heat transfer inefficiencies.

Water-Tube Boilers Delivers reliable foam suppression while maintaining circulation patterns and preventing deposition on critical heat transfer surfaces.

High-Pressure Steam Systems Specialized formulations for high-pressure applications where foam-related carryover can damage expensive turbine components and reduce generation efficiency.

Heat Recovery Steam Generators Tailored solutions for complex HRSG systems where variable loads and temperatures create challenging conditions for conventional defoamers.

Process Steam Applications Ultra-pure formulations for operations where steam quality directly impacts product quality and process integrity.

The Real Cost of Foam-Related Issues

Many facilities underestimate the financial impact of foam problems until experiencing significant consequences:

  1. Energy Losses: Foam-insulated heat transfer surfaces require 5-15% more fuel to maintain steam production

  2. Unplanned Downtime: Foam-induced carryover can necessitate emergency shutdowns for cleaning and repairs

  3. Reduced Equipment Lifespan: Deposits from foam-related carryover accelerate component deterioration

  4. Increased Maintenance Costs: More frequent cleaning and parts replacement due to contamination

  5. Production Losses: Process interruptions from inconsistent steam quality or emergency boiler shutdowns

Implementation: Strategic Foam Control

Transitioning to an optimized foam control program requires expertise. ETI’s comprehensive approach includes:

System Evaluation

Our specialists analyze your specific operational parameters, feedwater quality, pressure cycles, and existing treatment program to identify foam formation risks and optimal control strategies.

Precision Formulation

Based on your specific system characteristics, we recommend the ideal anti-foam solution from our product line or develop custom formulations for unique operational challenges.

Application Protocol Development

We design application protocols that ensure optimal dosing during steady-state operation and anticipate increased requirements during risk periods like startups, load swings, and water quality fluctuations.

Monitoring and Optimization

Our technical support team helps implement monitoring strategies to ensure continuous foam control and system protection while minimizing chemical usage.
