Uniquely suited to meet and exceed the requirements of waste-to-energy applications

Boiler Services

Waste-to-energy (WTE) boilers, biomass boilers, coal-fired boilers, black liquor recovery boilers and furnaces—they all need service and protection, and AZZ brings over 30 year's experience to the table. AZZ Specialty Welding's Unifuse® technology provides optimal surface protection for these critical pieces of equipment.

AZZ Specialty Welding originally developed the Unifuse® process in the mid 1980’s to address the extreme fireside corrosion issues that were common when WTE plants initially went into operation.  The technology has experienced many innovations throughout the years and continues to be the best practice in fireside boiler corrosion for WTE and Biomass units.  With the combination of industry leading automation equipment, and the development of proprietary alloys for erosion service, AZZ Specialty Welding continues to be the best solution for fireside corrosion issues in WTE and Biomass boiler plants.

AZZ Field Services is a full-accredited specialty construction company offering ASME and NBIC certifications for a wide range of boiler construction, maintenance and overhaul needs.
