ShellMax Global Ultra

The Shellmax Global Ultra Series boilers are designed with careful consideration to meet evolving needs, off ering user fl exibility and adhering to global standards. These boilers stand out with their unique and ultra-smart features, allowing users to select modules based on industry requirements, ultimately ensuring the highest effi ciency.

Thermax – Corrugated Furnace* for Reliability & Longer Life The furnace of boiler is subject to high pressure, diff erential temperature across the wall which causes bending stress due to diff erential expansion. Further, load fl uctuations & pressure variation create enormous thermal cycling across the furnace. International codes for boiler design have recommended corrugation to improve mechanical strength of boiler by increasing the moment of inertia.

Uniformity does not allow high stress concentration at discreet points, unlike bowling hoops / stiff ener rings. The entire corrugation process is carried out at an in-house facility, at normalizing temperature (hot forming at 950° to 980°C) to make sure the grain structure in the steel is oriented close to the parent metal to ensure physical properties.
