Quality Increase

Oxy-Conversion

Oxy-Fuel conversion means converting the furnace from air-firing to complete oxy-fuel firing. The increased combustion temperatures and heat transfer efficiency can result in glass quality increases. As the financial and technical considerations are quite complex, YIELD includes all required background information to calculate the financial and technical effects. The calculation includes factors like oxygen price, reduced wall losses, increased heat transfer, reduced flue gas volume and allows to compare liquid versus VPSA oxygen supply.

E-Boosting

Equipping furnaces with electrical boosting can result in an improved glass quality. With YIELD, the operator is able to calculate the costs related with the e-boosting considering CDM.

Glass Temperature Increase

The glass temperature is one of the key parameters in glass melting and is considered as critical. To increase the glass quality it is worth in some cases, to increase the glass exit temperature. But a temperature increase of 1% results in an increase of the energy consumption of up to 1.6%. The actual energy increase depends on many parameters. YIELD is able to calculate the potential energy increase based on a specified glass temperature increase.

Changes of glass temperatures always require a detailed analysis in advance to consider the effects on glass quality.

CFD/Consulting

The financial and technical effects of the presented cost reduction approaches can be calculated by YIELD. YIELD is a powerful tool to get evaluations of different technologies. The installation of the approaches require a more sophisticated analysis of limiting boundary conditions. We suggest to contact our engineering team at consulting@glassglobal.com, before starting the installation. We can help you by initiating CFD-Studies, contacting suppliers and providing sophisticated studies.
