Description
Electricity from steel plant by-products includes Waste Heat to Power (WHP) and Top Pressure Recovery Turbine (TRT). This electricity is a by-product of sinter production, which involves a series of processes such as mixing, sintering, and cooling of raw materials including iron ore fines, coke fines, and limestone. The data inventory is compiled from data sourced from multiple origins.
Activity Description
Sinter production involves a series of process activities including blending, sintering, and cooling of raw materials such as iron ore fines, coke fines, and limestone, ultimately forming lump ore suitable for blast furnace smelting. The unit process includes energy use (particularly fuel consumption in sintering), auxiliary material use, as well as waste treatment and pollutant emissions.
Process 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-saving but also beneficial to environmental protection. Blast furnace gas has high top pressure, so it can first pass through an expansion turbine generator for power generation before being supplied to gas users.
