BATCH / CULLET PREHEATING

Sustainability right from the start

Energy savings by using furnace waste gases

Rising energy costs mean production processes in glass production must be made as efficient as possible. One way to save costs is to use the waste gases from the melting process to preheat the batch and cullet. This enables a reduction in the melting energy requirement between 10 and 15 %.

Simultaneously, CO2 emissions can be reduced considerably and the capacity of production increased. A batch preheater can be planned as an integrated element of batch processing, but also as a retrofit later. As a pioneer of this technology, Zippe continues to refine its capabilities to offer you the most advanced systems that are also right for the environment.

The advantages of batch preheating are:

Reduction of melting costs
Reduction of emissions (CO₂ and NOx)
Increase in energy efficiency
Increase in plant productivity
Aging of the regenerators improves preheating efficiency over time (countervailing effect)

Zippe has been a pioneer in this technology since the early 1980s and today has the most extensive wealth of experience in the glass industry. Over the years, batch preheating technology has reached a very high level of development. The systems run reliably, are easy to operate, and have no moving parts inside, which contributes to low wear and tear and a long service life. The latest systems, such as the Advanced Batch Preheater (ABP®) can operate practically independently of variables such as the cullet ratio. We are therefore in a position to offer preheaters for mixtures/ batches with low cullet contents.

The facts – savings in concrete numbers:

10-15% savings in fossil combustibles/fuels and/or electrical energy
Increase in furnace tonnages in a similar range through accelerated melting process
