Refractory lining is one of the most critical elements in maintaining boiler performance, safety, and longevity. Over time, continuous exposure to high temperatures, fuel residues, and mechanical vibration causes deterioration of refractory materials — leading to heat loss, reduced efficiency, and potential system damage. At Thermo-Tech, we provide boiler refractory renewal services designed to restore full thermal protection and ensure safe, long-lasting operation.
Our process includes detailed inspection, removal of damaged refractory material, and installation of high-performance insulating linings. Using high-alumina castables, firebricks, ceramic fibers, and dense mortars, Thermo-Tech engineers rebuild the internal surfaces of boilers to OEM or class-approved standards. Each renewal project ensures maximum heat retention, corrosion resistance, and improved thermal efficiency.
All materials and installation methods are certified under IMO, BV, and DNV regulations, and every completed job is tested for heat distribution and structural stability before recommissioning.
Thermo-Tech’s Boiler Refractory Renewal Services cover marine and industrial units of all types — including steam boilers, thermal oil heaters, exhaust gas boilers, and incinerators. We conduct on-site relining, patch repair, and full insulation replacement depending on the system’s operational profile.
Each project begins with a heat stress assessment and condition mapping, ensuring that the new refractory materials match the system’s thermal load and combustion characteristics.
In addition to renewal, we perform anchoring system replacement, crack repair, and surface coating to protect against erosion and oxidation. Our specialized teams use advanced curing and drying procedures to ensure proper bonding and long-term durability.
Thermo-Tech also offers preventive maintenance programs for boilers, including thermal inspections and regular lining evaluations, helping operators avoid costly repairs or unscheduled downtime.
Thermo-Tech’s Boiler Refractory Renewal combines high-grade materials, precision engineering, and certified workmanship to deliver maximum protection and reliability.
Our expertise ensures that every boiler continues to operate efficiently, safely, and in full compliance with marine and industrial standards.
