Steel plant gas flows
Sankey diagram of blast furnace, coke oven and BOF gases in GJ/t of steel: flaring, natural gas purchases and energy to the power plant.
Simulator developed by José Geraldo da Silva Moreira · Energy-efficiency lab
Where do the gases of an integrated steel plant go?
Energy flows of process gases, in GJ per tonne of crude steel. Illustrative order-of-magnitude values.
Scenario
How to read it
- BFG is the largest energy flow, despite its low heating value.
- With an automated network, flaring drops and the power plant absorbs the gas, reducing natural gas purchases.
Typical situation
Simplified teaching models with order-of-magnitude illustrative values. Do not use them for design or operating decisions without validation against plant data.
