China Suppliers Factory End Fire Glass Furnace for Continuous Melting with Low Energy Consumption and Reduced Emissions
Description
If sufficiently dimensioned, the regenerators effect heat recovery of the melting end firing and thus ensure an optimal reduction of energy consumption of the glass melting process. Slightly larger regenerators than necessary are an investment for the future, reducing maintenance effort and common energy consumption increase due to ageing. Additionally this allows a furnace enlargement at the next furnace repair with reduced glass-to-glass time and costs, when reusing the basic design and lower part of the regenerator.
By designing the ports and superstructure properly very low emission values in respect of NOx and CO2 can be achieved. Since there is only one alternating flame in glass flow direction, its optimal adjustment is crucial for glass melting process. After furnace startup the first setting is usually done by experienced REFTECH® personnel for combustion optimization, ensuring an optimal melting performance from the start.
A weir wall built into the bottom of the melting end, also called barrier, and a deep refining part increase flexibility and glass quality.
The wall supports the convection in the glass bath, which improves melting. Additional electric boosting improves furnace flexibility and is advantageous in case of coloured glass production.
Additional lances or burners at the furnace sidewall can be mounted in order to lower NOx emissions by staged combustion or increase melting capacity by oxy boosting. Most common is the application of a pressurized air lance in order to lower NOx and generally improve melting. This technology is known as gg ENOx and can be applied also while furnace operation. It is most suitable to improve furnaces not showing a good performance.

Frequently Asked Questions
Q: How do regenerators help in reducing energy consumption?
Sufficiently dimensioned regenerators effect heat recovery of the melting end firing, ensuring an optimal reduction of energy consumption. Opting for slightly larger regenerators reduces maintenance efforts and controls energy consumption increases caused by ageing.
Q: How can NOx and CO2 emissions be minimized in the furnace design?
Very low emission values for NOx and CO2 can be achieved by properly designing the ports and the superstructure. Additionally, technologies like staged combustion or pressurized air lances (gg ENOx) can be implemented to lower emissions further.
Q: What is the purpose of a weir wall in the melting end?
A weir wall (or barrier) built into the bottom of the melting end, combined with a deep refining part, supports convection in the glass bath. This improves the overall melting process, flexibility, and glass quality.
Q: What are the benefits of additional electric boosting?
Additional electric boosting improves the flexibility of the furnace. It is particularly advantageous when producing coloured glass.
Q: What is gg ENOx technology and when is it used?
gg ENOx is a technology that applies a pressurized air lance to lower NOx emissions and improve melting. It can be applied during furnace operation and is highly suitable for upgrading furnaces that are not performing optimally.
