High-Temperature Coatings form Biomass

High-temperature coatings for biomass equipment protect steam boilers, Regenerative Thermal Oxidizers (RTOs), pellet manufacturing equipement, landfill flares, and biomass-powered emissions control systems from corrosion and heat damage. These coatings are formulated to perform under continuous high-heat operating conditions, repeated thermal cycling, and outdoor exposure typical of biomass and energy-sector equipment.

High Temp Coatings For Biomass Equipment

Manufacturers and facilities in the biomass processing industry use our coatings to protect equipment operating at elevated temperatures. Our coatings are used on Regenerative Thermal Oxidizers (RTOs), pellet manufacturing equipment, biomass-powered furnaces, biomass production equipment, landfill flares, and biomass-powered emissions control systems, and in other biomass applications.

 

Coatings for Steam & Industrial Boilers

Steam and industrial boilers operate under continuous high temperatures while being exposed to moisture, thermal cycling, and corrosive combustion byproducts. Our high-temperature coatings help protect boiler exteriors and auxiliary equipment from corrosion and heat-related degradation, extending service life and maintaining appearance in demanding operating environments.

Coatings for Pellet Manufacturing Equipment & Biomass Processing Equipment

Pellet manufacturing equipment and other biomass processing equipment operate under elevated temperatures and are often exposed to abrasion, moisture, and outdoor weathering. Our high-temperature coatings help protect equipment surfaces from corrosion and heat-related degradation, supporting long-term durability and reliable operation in demanding biomass processing environments.

Coatings for RTOs & Emissions Control Systems

Regenerative Thermal Oxidizers (RTOs) and emissions control systems are exposed to sustained high exhaust temperatures, thermal cycling, and corrosive combustion byproducts. Our high-temperature coatings provide durable protection for exterior surfaces, helping reduce corrosion and maintain long-term performance in demanding industrial environments.

Coatings for Landfill Gas Flares

Landfill gas flare stacks are exposed to extreme, cyclical heat along with outdoor weathering and corrosive combustion gases. Our high-temperature coatings help protect flare exteriors from corrosion and heat-related deterioration, supporting long-lasting performance in waste-to-energy applications.

FAQs
Q: What coating should be used on a Regenerative Thermal Oxidizer (RTO)?

A: Regenerative Thermal Oxidizers operate at sustained high exhaust temperatures and require a coating system formulated for continuous heat exposure and corrosion resistance. Forrest’s high-temperature coatings are designed to protect RTO shells and ductwork at temperatures up to 1100°F (593°C).

A: Each 13 oz. aerosol can produces approximately 100 marks, depending on the size of the mark, wood porosity, and application method.

Q: What paint can withstand steam boiler temperatures?

A: Steam boiler exteriors require a coating system rated for sustained high heat and repeated thermal cycling. Forrest’s 54H050 primer paired with a 64E or 62H290 topcoat is formulated for boiler and auxiliary equipment surfaces operating between 400°F and 1100°F (204°C to 593°C).

Q: Can high-temperature coatings protect landfill gas flares?

A: Yes. Landfill gas flare stacks are exposed to extreme, cyclical heat and corrosive combustion byproducts. Forrest’s zinc-enriched and high-temperature coating systems are formulated to protect flare stack surfaces up to 1100°F (593°C).

Q: How do I choose a coating for pellet mill or biomass processing equipment?

A: Coating selection depends on the equipment’s operating temperature, exposure to friction and weathering, and duty cycle. Forrest’s technical team can recommend a primer and topcoat system based on your specific pellet mill or processing equipment’s operating conditions contact us to discuss your application.

Q: How often do biomass and industrial equipment coatings need to be reapplied?

A: Reapplication timing depends on operating temperature, duty cycle, and environmental exposure. Facilities should inspect coated surfaces periodically for signs of wear or corrosion and consult Forrest’s technical team for a maintenance recoat recommendation specific to their equipment.
