where does combustion take place in a furnace
Furnace Fuel flows into the burner and is burnt with air provided from an air blower. There can be more than one burner in a particular furnace which can be arranged in cells which heat a particular set of tubes. Burners can also be floor mounted, wall mounted or roof mounted depending on design. The flames heat up the tubes, which in turn heat the fluid inside in the first part of the furnace known as the radiant section or firebox. In this chamber where combustion takes place, the heat is transferred mainly by radiation to tubes around the fire in the chamber.
Out of the Furnace After getting off work at a North Braddock, Pennsylvania, steel mill, Russell Baze catches his brother Rodney at a horse racing simulcast, where Rodney had just bet on a losing horse. Rodney reveals John Petty loaned the money to him. Petty owns a bar and runs several illegal games. Russell visits Petty, pays off some of Rodney's debt, and promises to pay Petty the rest with his next paycheck if Rodney has not yet paid it off. Driving home intoxicated, Russell hits another car, killing its occupants, including a little boy. He is incarcerated for vehicular manslaughter. While in prison he is informed that his ailing father has died and his girlfriend Lena has left him for the small town police chief, Wesley Barnes. Upon his release from prison, Russell returns home and resumes his job at the mill.
