PYRO BLOC M MODULE

TYPE

Refractory Fiber in Bloc Module

Description

The Pyro Bloc M Module and M&sup2 modules are a ceramic fiber lining system designed for high temperature furnaces that may also require corrosion barriers on the shell. The modules are manufactured from a high purity blend of raw materials to produce ceramic fiber grades:
  • R Grade (alumina-silica)
  • ZR Grade (alumina-silica-zirconia)
  • C Grade (alumina-silica-chromia)
Pyro-Bloc M and M² modules have better resistance to mechanical abuse than conventional blanket systems, and they do not sacrifice the effectiveness of the shell corrosion barrier. The Pyro-Bloc M and M² modules are held to the shell by pre-welded stainless steel studs, 316SS which offers superior creep resistance and chemical attack resistance versus 304SS. Special installation hardware and accessories allow the modules to be uniformly compressed. No other system on the market offers such a high degree of on-the-wall densities, which relates directly to high mechanical abuse resistance and long in-service life.

APPLICATIONS

  • Process heaters
  • Heat treating furnaces
  • Forge furnaces
  • Reformers, ethylene furnaces
  • Incinerators
  • All furnace linings requiring a pre-weld stud pattern or protective barrier against shell

FEATURES

  • Monolithic, edge-grained ceramic fiber module
  • Uncompressed densities from 10 – 15 pcf (160 – 240 kg/m3)
  • Installs quickly over coated shells with or without a vapor barrier
  • Installation techniques ensure high on-the-wall densities
