Cross Fire Glass Furnace in China - Leading Suppliers for Enhanced Glass Quality and Efficient Batch Processing Factory
Description
The regenerators, port necks and burners are positioned laterally. A separate chamber (sectional regenerators) together with an independent flue gas reversal system can be designed for each port neck. This ensures precise control of the furnace temperature over the entire length of the melting furnace. Often the flue gas from multiple port necks or even from all port necks is discharged via one chamber for cost reasons.
In case of environmental restrictions in respect to NOx emissions, this furnace type can be equipped with sideport burners in place of underport burners. Due to limited adjustability and port width, more ports are generally required. Because of the higher number of ports usually one or two regenerators are built on each side of the furnace in this case.
The regenerator chambers can be equipped with different checker types and qualities according to the position of each port. This facilitates the implementation of a furnace suitable for the raw materials used, with a long life and achieving the perfect melting process. A weir wall built into the bottom of the melting end, which is also called barrier, and a deep refining part increase the flexibility and glass quality.
This furnace type can be also equipped with electric boosting in order to increase melting capacity and flexibility.

Frequently Asked Questions
What is the maximum melting capacity of this furnace type?
This furnace type is capable of achieving a melting capacity of up to 750 tonnes per day (t/d).
How is precise temperature control achieved along the melting furnace?
By positioning the regenerators, port necks, and burners laterally. Additionally, a separate chamber (sectional regenerators) combined with an independent flue gas reversal system can be configured for each port neck to ensure accurate temperature control.
How does the furnace adapt to strict NOx environmental restrictions?
Under strict environmental regulations, the system can be equipped with sideport burners instead of underport burners. Since sideport configurations have limited adjustability and port width, more ports are typically required, usually resulting in one or two regenerators built on each side.
What is the purpose of the weir wall at the bottom of the melting end?
The weir wall (also known as a barrier), paired with a deep refining part, is designed to increase both the operation flexibility and the overall quality of the glass.
Can this furnace type be upgraded to increase melting capacity?
Yes, this furnace type can be integrated with electric boosting to further enhance its melting capacity and operational flexibility.
