Online inspection lets you assess furnace condition without losing production. Here is how it works in practice.
1. Use an existing opening
The cooled probe enters through a peephole or burner port while the furnace is running.
2. Cooling keeps the optics safe
Circulating water and compressed air protect the lens, and a wind curtain keeps dust and hot gas off the front.
3. What you can see
- Melt surface and batch line
- Crown and superstructure condition
- Flame shape and combustion
- Refractory erosion and corrosion
