01 / Overview

High Temperature Inspection for Float Glass Furnaces

A float glass furnace runs continuously for a campaign of 10–15 years at 1500–1600°C. Any unplanned stop is extremely costly, so internal condition has to be checked while the furnace is hot.

Our high temperature endoscope inspects the melter, regenerator, throat and tin bath through existing ports during operation — letting you track refractory wear and plan repairs before they become emergencies.

02 / Why It Matters

Why Float Furnace Inspection Is Critical

A float line is exposed to:

Continuous 1500–1600°C operationVery long furnace campaignGlass & alkali vapour attackRegenerator checker blockageTin bath roof drip & tin oxideThermal & mechanical erosion

Hidden wear means lower pull, higher fuel use and the risk of a forced hot repair. Regular hot inspection keeps the campaign on plan.

03 / Inspection Targets

What We Look For

Melter Crown & Sidewall

Erosion, drip and thinning of the melting end refractory.

Regenerator Checkers

Blockage, slumping and corrosion of checker brick.

Port & Burner Area

Thermal impact and refractory damage around the ports.

Throat & Waist

Wear at the transition between melter and working end.

Working End / Refiner

Refractory condition where glass conditions before forming.

Tin Bath Roof

Roof refractory drip and tin-oxide build-up over the bath.

04 / Inspection Points

Float Line Inspection Points

Melting Furnace

Crown, sidewall and basin refractory under the melt.

Regenerator

Checker chambers and crowns for blockage and wear.

Ports

Burner ports and port necks.

Throat / Waist

Submerged throat and waist transition.

Working End

Refiner and distributor refractory.

Tin Bath

Bath roof, structure and entrance/exit areas.
