What's the difference between flue and furnace?

Flue


Definition:

  • (n.) An inclosed passage way for establishing and directing a current of air, gases, etc.; an air passage
  • (n.) A compartment or division of a chimney for conveying flame and smoke to the outer air.
  • (n.) A passage way for conducting a current of fresh, foul, or heated air from one place to another.
  • (n.) A pipe or passage for conveying flame and hot gases through surrounding water in a boiler; -- distinguished from a tube which holds water and is surrounded by fire. Small flues are called fire tubes or simply tubes.

Furnace


Definition:

  • (n.) An inclosed place in which heat is produced by the combustion of fuel, as for reducing ores or melting metals, for warming a house, for baking pottery, etc.; as, an iron furnace; a hot-air furnace; a glass furnace; a boiler furnace, etc.
  • (n.) A place or time of punishment, affiction, or great trial; severe experience or discipline.
