An Overview of Refractory Repair

large-boilerBoiler refractories are often overlooked, but they are a leading cause of fuel inefficiencies and boiler shutdowns. They are absolutely crucial to maintaining your boiler and making sure you are getting the most out of your equipment. In other words, it pays to pay attention to refractories. Refractory installation and refractory repair should be performed by a trained boiler service technician, but we’ll give you the key facts so you can learn more about refractory issues and what to do about them.

What Does Refractory Refer To?

Refractories are heat resistant materials that make up the linings of equipment like furnaces and boilers. Refractories often take the form of tiles or brick in industrial boilers. They are more heat resistant than metals and can withstand extreme pressure. They must also be able to endure chemical processes and the general wear that comes from frequent and high-intensity usage.

How Does Refractory Material Relate to Boiler Performance?

Your boiler’s fuel efficiency and your boiler’s combustion efficiency are closely related: you need good combustion efficiency in order to get the most out of your fuel. One way to make sure that your boiler is performing at the peak levels is to invest in quality refractories. Refractories work by holding heat in, preventing thermal loss during the combustion process. Refractories also help maintain heat in the boiler even when it is not firing, which means the next time the boiler is on, you are not working with a completely cold vessel and it will heat up much more quickly.

The Refractory Repair Process

Issues with your boiler’s refractory may include cracking, difficulty with refractory doors, pressure vessel leaks, or damaged seal joints and holes. Any sign of damage or drops in performance may indicate that a refractory repair is in order.
