Heating Value and Waste Gas Flow-Controlled Exhaust Gas Combustion for a 150-ton RH-TOP Degasser at Big River Steel (Room 207 A)

Big River Steel started production in 2016. The customer selected an RH-TOP degasser mainly with the objective of producing ultralow-carbon steels by performing an efficient decarburization process. This process generates considerable amounts of CO. U.S. federal regulations require the burning of combustible process gases with a heating value of at least 200 BTU/SCF. To comply with this regulation, a new type of flare stack burner has been developed, which combusts CO-containing exhaust gases and reduces the environmental impacts in the form of CO2 emissions.
