Online hot spot refractory repair is crucial to maintain multi-million ringgit industrial boilers, incinerators, and furnaces from thermal damage.
Operating temperatures can reach about 1650°C hence refractories will wear out eventually.
So, proper maintenance of the processing equipment is crucial to prevent refractory failure and downtime on operations.
However, if you notice any damages to your refractory, one reliable solution is online hot spot refractory repair.
What are Hot Spots?
In general, hot spots are damages to refractory internal insulation or ceramic fiber lining.
Mainly, it occurs due to the intense heat applied to the refractory lining wall possibly caused by ineffective refractory.
Nonetheless, hot spots on refractory installations are fairly common in boilers, furnaces, and other refractory-lined equipment.
If you’re wondering how to reduce temperature of hotspot for furnace casing, you can learn here.
Where do Hot Spots Occur?
Basically, furnace hot spots on refractory installations often occur in boilers, furnaces, and other refractory-lined equipment.

Furnace Hot Spot Refractory Repair Procedure
How to Repair Refractory with Online Hot Spot Repair?
Firstly, the furnace remains online. Then, refractory engineers drill holes into the casing plate of the refractory lining.
Afterward, the refractory contractor injects specially formulated mould to fill up the cracks and gaps inside the damaged refractory lining.
In time, the injected mould will cool down immediately inside the insulation lining.
Then, the refractory professionals will thoroughly check the refractory casing repairs. As a result, they will identify any unfilled gaps that can impact the refractory effectiveness.
Once everything is assessed and approved, the refractory experts will close the drilled holes. Then, they will apply additional refractory anchors for added support.
Importance of Online Hot Spot Refractory Repair
In essence, a successful online hotspot repair of a refractory insulation lining is very beneficial to the company.
Because the high-temperature equipment is not shut down, daily operations can still run as usual during the boiler refractory repair.
Also, online hot spot repairs can help companies avoid at least 2 weeks of shutdown and pro-longed maintenance. Not to mention, this system and technology can avoid plant having any unplanned shutdown which can save up thousands and millions of revenue from the loss of production.
So, before you face total shutdown, extended maintenance, and costly expenses, contact a refractory services company for expert furnace refractory repair.
