A Divided Blast Cupola is a vertical furnace widely used in foundries to melt cast iron and related alloys. Unlike conventional cupolas, it uses a divided air blast system where air is supplied at multiple levels through tuyeres. This ensures:

• Complete combustion of fuel
• Better heat distribution
• Reduced coke-to-metal ratio
• Higher melting efficiency

This innovative design makes the divided blast cupola a more economical and eco-friendly alternative to traditional melting methods.

The divided blast system introduces preheated air at different levels of the furnace.

• Lower-level tuyeres supply the main combustion air for coke burning.
• Upper-level tuyeres re-ignite unburnt gases, ensuring complete fuel utilization.

This dual-blast arrangement improves thermal efficiency, fuel economy, and melting consistency, making it one of the most effective foundry melting furnaces.
