Wuxi Huali Juneng Equipment Co., Ltd. provides complete hydrogen-based direct reduced iron (H-DRI) process equipment for the steel industry's low-carbon transition. By replacing traditional coke with hydrogen as the reducing agent, the process significantly reduces carbon emissions from ironmaking. The company has leading technical advantages in key equipment such as high-temperature hydrogen heating systems, gas-based shaft furnaces, and heat recovery systems, supporting the steel industry's carbon-neutral goals.
Gas-Based Shaft Furnaces
The gas-based shaft furnace manufactured by Huali Energy is the core equipment of hydrogen metallurgy. The furnace body uses specialty heat-resistant alloy linings for long-term stable operation in high-temperature reducing atmospheres. Its design fully considers uniform gas distribution and smooth material descent to ensure efficient reduction reactions.
Gas Heaters
Large gas heaters heat reducing gas to process temperatures of 900-1050°C for hydrogen-based reduction. Using advanced radiant tube technology and high-temperature alloy tube bundles, these heaters offer high thermal efficiency, long service life, and the durability required for continuous production.
Heat Recovery Systems
Supporting high-temperature waste heat recovery systems recover heat from reduction off-gas for reducing gas preheating and steam generation. The system delivers significant energy savings, reducing process energy consumption by more than 20% and improving overall economics.
Hydrogen Metallurgy Equipment Application Cases
Hydrogen Metallurgy Demonstration Project for a Steel Group
Huali Energy provided core equipment for a million-ton hydrogen metallurgy demonstration line operated by a major domestic steel group. Using full-hydrogen reduction, the project can cut carbon emissions by more than 70% compared with traditional blast furnace processes and has become a benchmark for industrialized hydrogen metallurgy in China.
