Description
Electricity from steel plant by-products includes Waste Heat to Power (WHP) and Top Pressure Recovery Turbine (TRT). WHP is a technology that converts excess thermal energy from production processes into electrical energy. WHP is not only energy-efficient but also beneficial for environmental protection. The blast furnace gas has high top pressure and can first pass through a steam turbine generator for electricity generation before being supplied to gas consumers. This dataset includes major raw materials, auxiliary materials, energy inputs, atmospheric emissions, waterborne discharges, and waste from the production process. Infrastructure such as production equipment manufacturing and plant construction is not included within the system boundary of this dataset. This dataset is inferred from multiple data sources. The coke production activity includes coking, cooling, screening, and other process steps. Electricity is a by-product of this process.

Process Description
Electricity generated from steel plant by-products includes waste heat power generation and pressure difference power generation. WHP is a technology that converts excess thermal energy from production processes into electrical energy. WHP is not only energy-saving but also beneficial for environmental protection. Blast furnace gas has high top pressure; it can first pass through an expansion turbine generator to generate electricity before being supplied to gas consumers.

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.
