Glass Annealing
Burners for Glass Annealing & Forming
Controlled heat for glass annealing lehrs and forming, where temperature precision defines quality.
How Zhongli Weiye equips this industry
Glass annealing and forming depend on holding precise temperatures along a lehr or furnace. We supply gas and dual-fuel burners with modulation matched to the glass line's profile.
A lehr holds a falling temperature curve from the forming zone to the cold end; the burner must modulate smoothly so the glass relaxes without stress rather than cooling in steps.
For forming furnaces we size for the melt temperature and the campaign length, and we keep spares for the flame scanners because a lehr stoppage freezes the whole line.

Buyer Questions
Glass Annealing FAQs
Can the burner hold the lehr profile?
Yes — we match modulation range to the annealing temperature curve so the belt speed and cooling stay in step and breakage stays low.
What fuel for glass lines?
Gas gives the cleanest flame for a lehr and is preferred where piped; dual-fuel protects a continuous float or container line against a supply cut. We size by line layout and available gas pressure.
Is control included?
Controllers and flame detection are part of the matched set, and we keep the critical flame-scanner spares because a lehr stoppage freezes the whole glass line.
Firing this duty?
Send the lehr length, profile and line speed and we size the burners and controls.
