Boiler Technology

Water Skirts and Ash Hoppers are often found to be a problem area in boilers.  These areas show much more wear that would be expected.

 

This happens because normal refractory concrete loses strength in warm wet conditions when the cement bonding phases convert to give a material with much lower strength.

 

Durocast have developed Duroshield P which has geopolymer bonding which is resistant to conversion.

This is a strong, rapid hardening product which is resistant to clinker build up.  If necessary steel fibers can be added to enhance the impact resistance.

 

The material is easy to install and can be mixed in a normal pan mixer or installed by pneumatic pump. These  products can be supplied in a coarse or fine grade to meet the application requirement.

 

Please contact Durocast for more information.
