Furnace Life-Time

Oxy-boosting

The installation of additional oxy-fuel burners can decrease the fuel consumption. The improvement of the heat transfer can be used to lower the refractory temperature. Oxy-boosting can additionally be used to compensate a decreasing productivity of the furnace caused by aging. YIELD allows to calculate the technical and financial aspects of oxy-fuel boosting and contains all required technical and financial background information. The calculation considers factors like oxygen price, reduced wall losses, increased heat transfer, reduced flue gas volume and allows to compare liquid versus VPSA oxygen supply.

Oxy-Fuel Conversion

Oxy-Fuel conversion means converting the furnace from air-firing to complete oxy-fuel firing. The increased heat transfer efficiency finally results in a lower refractory temperature and/or profit 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 furnace life time extension, due to refractory temperature reduction. With YIELD, the operator is able to calculate the costs related with the e-boosting considering CDM.

Glass Temperature Reduction

The glass temperature is one of the key parameters in glass melting and is considered as critical. But nevertheless, in some cases it is worth to reduce the glass exit temperature. The actual profits of glass temperature reduction depends on many parameters. YIELD is able to calculate the potential energy reduction based on a specified glass temperature reduction. Changes of glass temperatures always require a detailed analysis in advance to consider the effect on glass quality.

Combustion Temperature Reduction

The combustion temperature is measured in the glass melting process and is considered as critical. But nevertheless, in some cases it is worth to reduce the glass exit temperature. A temperature decrease of 1% is reducing the energy consumption by up to 1.6%. The actual energy reduction depends on many parameters. YIELD is able to calculate the potential energy reduction based on a specified glass temperature reduction.

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

CFD/Consulting

The financial and technical effects of the furnace life time extension approaches can be calculated by YIELD. YIELD is a powerful tool to get evaluations of different technologies. A prediction of the reachable furnace life time with YIELD , however, is not yet available. We suggest to contact our engineering team at consulting@glassglobal.com. We can help you by initiating CFD-Studies, contacting suppliers and providing sophisticated studies.
