China Cross Fire Glass Furnace Suppliers - Enhanced Uniform Heating and Superior Glass Quality from Our 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 capacity of this furnace type?
This furnace type features a high specific melting output with a capacity of up to 750 tonnes per day (t/d).
How is precise temperature control achieved along the furnace?
By positioning the regenerators, port necks, and burners laterally, and designing a separate chamber (sectional regenerators) with an independent flue gas reversal system for each port neck.
How can the furnace comply with strict environmental NOx emission limits?
To meet environmental restrictions, the furnace can be equipped with sideport burners instead of underport burners, typically requiring one or two regenerators on each side.
What is the purpose of the weir wall and deep refining part?
A weir wall (barrier) built into the bottom of the melting end, combined with a deep refining part, increases the system's flexibility and ensures higher glass quality.
Can the melting capacity and flexibility be further increased?
Yes, this furnace type can be equipped with electric boosting to further increase both the melting capacity and operational flexibility.
