Description
Coke is primarily used in the blast furnace ironmaking process in the metallurgical industry to reduce iron oxide in iron ore into metallic iron; steam is a key form of energy widely used for heating, electricity generation, and cleaning in many industrial and commercial applications. This dataset includes major raw and auxiliary materials, energy consumption, atmospheric emissions, waterborne emissions, and waste generated during the production process. Infrastructure such as production equipment manufacturing and plant construction is not included within the system boundary of the dataset. The dataset was compiled from data sourced from multiple origins. Steam is a by-product of the coke production process.
Activity Description
The production activity of coke includes processes such as coking, cooling, and screening.
Process Description
Steam is a critical energy form in many industrial and commercial applications, widely used for heating, power generation, and cleaning purposes. High-quality steam is essential to ensure process efficiency, equipment performance, and operational safety. Steam pressure, temperature, and purity are key indicators determining its suitability and efficiency.

Technology comment
Coking involves heating coal to above 1000°C under oxygen-deficient conditions, causing it to undergo pyrolysis reactions that produce coke and by-products (such as gas and tar). After coke formation, it requires cooling, screening, and quality inspection.
