Hot Blast System

The hot blast system is critical for the blast furnace process, delivering preheated enriched air to the blast furnace ensuring efficient combustion and optimal thermal performance. Danieli Corus has continuously evolved its hot blast system technology, integrating advanced combustion designs, automation, and energy recovery systems to meet the demands of modern steelmaking. The cyclic nature of the hot blast stoves imposes highly dynamic conditions on the refractory design. The tendency to move towards higher online hot blast temperatures has made the refractory design even more critical because continuous operation at these high temperatures requires exceptional stability of the steel shell and refractories.

Custom and Scalable Design

Whether retrofitting existing stoves or designing new installations, our hot blast system solutions are modular and adaptable. Our solutions are highly customizable to the requirements of your blast furnace. Focused on achieving the lowest cost without compromising the quality and performance of the system.

Mature and proven Combustion Technologies

Our stoves represent the latest generation of combustion optimized to minimizing NO_x and CO emissions and limiting the excess air required for proper combustion. We can supply all types of combustion technology and will determine the best fit for your blast furnace together.

Lifetime Extension

Your hot blast system is critical in providing hot blast to your blast furnace, therefor it requires trouble free operations of your hot blast stoves. We at Danieli Corus know how to design our products with this in mind, but more importantly are able to assess your current state of equipment and together develop a maintenance(check–up) plan. Focusing on short and long term investments to get the maximum out of your available equipment, we can do this for the internal, externals and rotating equipment.

Dome Combustion Technology

The first hot blast system incorporating dome combustion technology in India was successfully commissioned with Danieli Corus design. With all of the design features that have given Danieli Corus hot blast stoves their exceptional lifetime capability incorporated, dome combustion technology has now reached maturity.

This milestone project set a new benchmark in performance and reliability, and its learnings are now embedded in all future designs.
