Careers Circulating Fluidized Bed (CFB) Boiler Tube Erosion
HVTS® Claddings for CFB Boiler Tubes
IGS leverages decades of experience with over 500 Circulating Fluidized Bed (CFB) Boiler High Velocity Thermal Sprayed (HVTS®) cladding applications to stay at the forefront of maximizing run time and minimizing outage frequency and cost for CFB Boilers globally. IGS HVTS® cladding has been successfully used over the past decade to provide scalable (we adjust cladding thickness to meet specific wear rates in different locations), proactively manageable and fully refurbishable boiler tube protection from fly ash erosion and fireside corrosion. Our service renders mechanical repair of boiler tubes in Circulating Fluidized Bed Boilers an unnecessary practice.
Our Experience Cladding Metal Inside CFB Boilers
IGS is the pioneer in the use of Thermal Spray claddings in CFB boilers. We have completed over 500 CFB applications over the past two decades. Having completed so many applications over so many years uniquely positions IGS as the knowledge leader in materials, application technology, installation, refurbishment and operating methods. Simply stated, we are the best positioned to know what works and what does not in many varying CFB Boiler types burning a wide range of fuels across the globe. Where others may be experimenting, IGS has trusted and proven solutions.

Optimized Solutions for CFB Boiler Tube Wastage Protection
Over the past decade, we have leveraged this experience and knowledge to develop unique materials and methods to provide reliable and predictable protective barriers in the most challenging CFB boilers globally. We have learned that:
- For the use of thermal spray coatings to make sense economically, they must be managed proactively so as not to expose underlying substrate material. Investing in thermal sprayed coatings and having to expend time and money on tube restoration is not optimal. IGS has proven success in accomplishing this.
- Materials need to have specific properties to successfully protect boiler tubes reliably over multiple outage cycles, and for the life of the boiler. Hardness, toughness and residual stress properties are among some of the critical characteristics that determine whether coatings will wear in a controlled manner, and not cause secondary problems in the furnace such as accelerated wastage of the tubes at the coating interface, or accelerated localized wear should the coating failure in localized areas.
IGS Cladding Prevents Accelerated Localized Wear of CFB Waterwalls
- Managing long-term boiler tube protection is a larger challenge than just the initial application. Unlike many environments where protective claddings or coatings are used, in CFB boilers, the boiler tube protection system such as IGS HVTS® cladding is a sacrificial layer. This means it must be proactively refurbishable to be effective. IGS creates value for its clients not only through the provision of skilled personnel and proprietary fit for service HVTS® cladding solutions but also through expert inspection and wastage modeling. We specify what materials, at what thickness should be applied where both on initial application and periodic refurbishment. These specifications ensure long-term dependable performance.
Testimonial
Good communication. Job hazard analysis was well documented and the thermal spray method statement was clear and comprehensive. IGS was on time and provided daily job progress reports.
