AI Technical Summary

Technical Problem

The existing refractory materials on the inner wall of hot blast stoves are easily damaged under high-temperature conditions, and existing protective measures are costly and have limited effectiveness.

Method used

An air storage layer and ventilation holes are set on the inner wall of the furnace. Cooling air is delivered through the cooling air inlet pipe to reduce the temperature of the inner wall. Dustproof components prevent furnace ash from entering the air storage layer. Combined with the X-shaped reinforcing block support structure, furnace ash accumulation is prevented.

Benefits of technology

It effectively reduces the temperature of the furnace inner wall, extends the service life of refractory materials, ensures smooth ventilation of the air storage layer, avoids ash accumulation, and improves usability.
