Cullet Preheater

Energy-saving equipment development

A cullet is a lump of glass made from collected crushed glass.
In a normal glass melting furnace, cullet is mixed with raw material at 40% ratio.

Preheat reduction ratio

This device recovers heat by passing high-temperature exhaust gas through the cullet and preheating the raw material.
By using this device, in case the cullet ratio is 100%, we have succeeded in reducing fuel consumption by 28% compared to the case where cullet preheating is not performed.
