China Suppliers Factory End Fire Glass Furnace - Energy-Efficient Continuous Melting with Low Carbon 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
How do regenerators help in reducing energy consumption? +
Sufficiently dimensioned regenerators facilitate heat recovery from the melting end firing, ensuring an optimal reduction of energy consumption in the glass melting process. Investing in slightly larger regenerators also helps mitigate energy consumption increases caused by ageing.
What are the benefits of installing slightly larger regenerators? +
Larger regenerators reduce overall maintenance effort and prevent energy efficiency loss over time. Furthermore, they allow for future furnace enlargement during repairs with reduced glass-to-glass time and cost by reusing the basic design and lower part of the regenerator.
How can NOx and CO2 emissions be minimized in the furnace? +
Very low emission levels of NOx and CO2 can be achieved by properly designing the ports and superstructure. Additionally, installing a pressurized air lance (gg ENOx technology) or mounting extra burners at the sidewall for staged combustion can further lower NOx emissions.
What is the function of a weir wall (barrier) in glass melting? +
A weir wall built into the bottom of the melting end, paired with a deep refining part, increases both glass quality and operational flexibility. It supports the convection currents in the glass bath, which directly improves the melting process.
What is gg ENOx technology and when is it applied? +
gg ENOx is a technology that uses a pressurized air lance to lower NOx emissions and improve general melting performance. It is highly suitable for upgrading underperforming furnaces and can be safely applied while the furnace is in operation.
