  • Furnace - Wikipedia

    A furnace is a device used for high-temperature heating. The name derives from Greek word fornax, which means oven. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces. In American English and
