Refractory

Relining and repair for boilers, furnaces and burner throats.

Refractory failure shows up as fuel-per-tonne creep long before it shows up as visible damage. We reline and repair refractory in boilers, furnaces and burner throats to the original or an upgraded specification.

What’s included

  • Boiler refractory replacement
  • Furnace refractory relining
  • Burner throat refractory
  • Refractory repair and hot-repair
  • Full relining — hearth, walls, roof, soaking zone

Frequently asked

Localised hot-repair and gunning can often be done without a full cold-down; full relining needs the equipment cold.

5–14 days for a furnace, depending on zone count and lining type; boiler refractory work is scoped as part of a shutdown.

Sometimes — repeat failure in the same zone can point to a combustion or thermal cycling issue worth investigating rather than just relining again.
