Fire-resistans Modular systems Superwool® XTRA Module Systems
Description
Superwool XTRA has been developed to work as a module system. This includes Stack module comprising strips of high quality spun fibre blanket, compressed and banded with plastic strips and including two stainless steel tubes mounted transversely through the strips remote from the hot face. They can be anchored to the furnace casing in any one of three standard versions, Y, M, and T.
In the Y module, the tubes are connected with a central, internal yoke, which includes a stainless steel stud and aluminium extension tube. This version is installed directly onto a metal plate casing, without pre-welding, using the special Pyro Bloc stud gun. It offers the fastest installation rates of any currently available modules.
The M module also includes the central yoke, which is fitted onto pre-welded studs using the special M module stud locating equipment.
The T module is anchored with a pre-studded, external, side-fix yoke.
M and T modules are used where the lining specification calls for either or both a backing blanket and anticorrosion treatment of the casing.
Type
Stacked blanket anchored modules. Blankets for expansion joints and batten strips.
Classification temperature
Superwool XTRA Module Systems: 1450°C (EN 1094-1) 2600°F (ASTM C892-17).
Maximum continuous use temperature
Superwool XTRA Fibre: 1300 - 1325°C (2372 - 2417°F)
The maximum continuous use temperature depends on the application. The wide range of available densities and thicknesses allow for the most effective deployment of the superior thermal characteristics in a wide variety of applications.
Features
Pyro-Stack modules combine some of the features of Pyro-Bloc and convoluted blanket modules:
• The Pyro-Stack module maintains the lightweight, thermal efficiency and resistance to thermal shock, which are characteristic of ceramic fibre linings
• They share the flexibility of anchorage and ease of installation of the Pyro-Bloc modules the decompression of the blanket gives tightly sealed inter-modular joints
• The resilience of the blanket can accommodate some flexing of the furnace casing without opening gaps between modules
• The resilient blanket is resistant to mechanical damage
• Y Modules – Fast installation. All welds automatically torque tested. One-step installation
• M and T Modules – Allow use of backing insulation and casing treatment
Module compression guaranteed. Simple fixing components. Use standard, commercially available welding equipment
Benefits
There are some specific benefits of using Superwool XTRA Pyro-Stack modules:
• Excellent thermal insulating performances
• Exonerated from any carcinogenic classification under Nota Q of directive 97/69EC, certificate available on request
• Does not form crystalline silica when exposed to high temperatures
• Excellent resistance to chemicals and pollutants, especially alkali metals
• High thermal coefficient of expansion to counteract shrinkage in operation
• Excellent thermal stability with time
• Low heat storage
• Immune to thermal shock
• High resistance to erosion when used in stack modules; no damage up to 50 m/sec at 1250°C (2282°F)
• Resistant to water and steam
