01 / Overview

High Temperature Internal Inspection for Glass Furnaces

Glass furnaces run continuously at extreme temperatures, making internal inspection difficult and costly with conventional shutdown methods.

Our high temperature endoscope lets operators inspect furnace interiors during operation or controlled-temperature conditions — improving reliability, maintenance planning and production stability.

02 / Why It Matters

Why Glass Furnace Inspection Is Important

Glass furnace refractory structures are exposed to:

Continuous high temperaturesChemical attack from molten glassThermal cycling stressMechanical erosionLong-term structural deformation

Without timely inspection, hidden damage leads to reduced efficiency, higher fuel consumption and premature furnace shutdown.

03 / Inspection Targets

What We Look For

Refractory Brick Erosion

Gradual loss of refractory thickness from thermal and chemical attack.

Cracks & Structural Damage

Visible cracks and potential expansion zones.

Crown Condition

Roof areas inspected for deterioration and instability.

Glass Contact Zone

Brick condition in areas exposed to molten glass.

Deposits & Build-Up

Internal accumulation affecting heat distribution.

Surface Spalling

Localized refractory peeling caught before major failure.

04 / Inspection Areas

Areas Inside Glass Furnaces

Furnace Crown

Roof brick condition and structural stability.

Sidewall

Erosion and thermal wear.

Port Area

Burner-related thermal impact.

Melting Zone

Refractory exposure and degradation.

Regenerator

Blockage and refractory damage.

Throat Area

Transition sections checked for abnormal wear.
