3D CFD flow simulation-driven refractory engineering for Jiugang Iron & Steel Group’s 1080 m³ hot blast stove — verified 15+ years service life. Our Hot Blast Stove Refractories are engineered for large-capacity stove service conditions.
Hot Blast Stove Technology Background
The hot blast stove is a series of hot blast stoves with excellent structural stability developed on the basis of Kalukin two generations of hot blast stoves. Its shape and structural characteristics mainly inherit two major structural forms: the large-dome hot blast stove with spherical vault and annular or sleeve burner, and the small-dome hot blast stove with conical dome and bell-shaped pre-combustion chamber.
Hot blast stove burners feature rapid uniform premixed combustion, oxygen-enriched combustion-supported staged combustion, low-oxygen grading and low-nitrogen combustion, and partially controllable thermal storage (checker brick or refractory ball) premixed combustion.
Such a hot blast stove achieves rapid and uniform mixing with high-intensity reflux preheating combustion, ensuring high heat efficiency, high heat strength, and high air supply temperature, achieving fuel savings, investment reduction, exhaust gas temperature reduction, and harmful gas emission reduction. Our Hot Blast Stove Refractories deliver complete turnkey solutions for modern hot blast stove installations.
