High Temperature Furnace, Kin, Fired Heater linings where modular construction is preferred. Quick installation and easy maintenance are the advantages of using modules. Used for Lining at Shuttle & all type of kiln.

       
Z Block Module
       
       
   

The Z-Block modules are folded modules available in two design configurations. Z-Block I has a slide channel that  runs  perpendicular to the  folds, it slides  onto a disc or  clip  that  has been  attached  to the  steel  casing.
Z-Block II has a C-Channel that runs parallel to the module folds. This C-Channel is typically attached to the steel casing with a welded stud and nut. Other design configurations are also available such as Z-Block III. Please refer to our Sale Office for more information.

 
 
Pyro Block Module
       
       
   

Thermal Ceramics' Pyro-Bloc modules are the only "monolithic" ceramic fiber modules on the market. Manufactured from monolithic ceramic fiber logs, they are available in three grades, R Grade, ZR Grade and C Grade and in uncompressed module densities up to 240kg/m³ (15 PCF). Pyro-Bloc modules combine the insulating material advantages of ceramic fiber with rapid furnace installation. The monolithic fiber is easy to cut to fit around openings and modify in the field. In addition, these modules are lightweight, have low heat storage and provide durable service.

Application Areas

Hot face veneering for existing furnaces, kilns and heaters where the lining is in a reasonably good condition and does not require immediate replacement. Veneering offers reduction in heat loss, leading to fuel savings. Further, the life of refractory lining is extended due to protection offered by ceramic fiber. Available for Temperature 1260°C & 1425°C. Used for Existing Applications where Lining is in a Reasonably. Offers Reduction in Heat loss, Leading to Fuel Saving.

     Many kinds of anchor installation

 
       Folded blanket will impact tight with each other in differently way without gaps after release from packing.  
       Elastically fiber blanket can withstand mechanical force  
       The elasticity of fiber blanket could make up distortion of furnace casing and with   gaps between modules  
  10       Because of the light weight, the decalescence capability is low as the insulation materials.  
  11       Low thermal conductivity can save much energy.  
  12       Can be betaken immediately as soon as being installed, for there is no need to be dried and maintained.  
  13       The Anchor system should be far away from the hot surface of the modules and kept in the lower temp.  
       
  Application Range :  
       
   

     Furnace lining in all kinds of industry furnaces and heating equipment in the industry of metallurgy,

 
         petrochemical, construction and machinery & ferrous metal industry.
