Boost Boiler Efficiency with Refractory Repair


Refractory is heat-resistant materials that are used to line the boiler to help it retain heat. This prevents thermal loss during boiler operation even during pre and post purge. When refractories are in good shape, they store heat and avoid thermal loss during the combustion process, thus helping your boiler run as efficiently as possible.

Refractory that is cracked or old can droop or fall will result in significant heat loss and flame impingement. Additionally, refractories aid in keeping the boiler warm even when it is not operating, allowing you to use the boiler’s energy the next time it does. 

PBBS Equipment can repair the rear head/door of your firetube boiler to like-new condition.

First, PBBS technicians remove the subpar, defective refractory material.

Then the relining process begins by applying the insulating layer(s) per the boiler manufacturers recommendations and prepare for the new refractory material installation.

After the refractory is installed, PBBS installs a custom bake-out controller and bakes out the material in accordance with the material recommendation in the relining process.
