Similar to the end fired furnace, the regenerative cross fired furnace provides low energy consumption and high flexibility in terms of pull change. However, this type of furnace can be built with bigger melting areas due to the shorter flame length compared to the end fired furnace. Therefore the cross fired furnace is normally used for furnaces with high capacity or where the existing building does not allow for an end fired furnace.
The furnace can be used for container glass, table ware, cosmetic glass, pharmaceutical glass, sheet glass, solar glass, sodium-silicate glass, tubing and lighting glass.
According to the glass quality, furnace capacity, raw material specifications and the type of glass, each furnace is perfectly designed and tailor-made according to the requirements of the glass industry.
The regenerators, burner ports and burners are situated laterally. For each burner port a sectional regenerator chamber can be designed together with a damper at the waste gas channel. This enables the precise control of the tank temperature along the melting process inside the tank.
Specialised know-how and extensive experience go into the design of the furnace port neck, tank superstructure, doghouse and burners to achieve the most economical furnace in terms of energy and emission. Regenerators can be equipped with different types of checker works and qualities to suit perfectly to the melting process and used raw materials to achieve long furnace lifetime.
A barrier wall incorporated into the melting end bottom and an additional step for a deeper refining area increase the flexibility and the quality of the glass.
The furnace can be operated with natural gas, LPG, coal gas, biogas and oil. In addition, there is the possibility of installing specially developed melting assistant devices such as electrical boosting, bubbling system or throat boosting.
