An enclosed structure in which material can be heated to very high temperatures, e.g. for smelting metals
A furnace through which a natural current of air carries the flame from the burning fuel at one end, over the charge, and out at the other end.
A furnace or (later) a heater or boiler in which the combustion of gas is used as a source of heat.
An oil-burning domestic stove.
A furnace containing pots for glassmaking, or in which crucibles are heated.
Another term for electric-arc furnace.
A furnace in which iron is smelted.
A smelting furnace in the form of a tower into which a blast of hot compressed air can be introduced from below. Such furnaces are used chiefly to make iron from a mixture of iron ore, coke, and limestone
An apparatus for obtaining high temperatures from the energy of atoms; specifically = nuclear reactor.
A furnace in which the object being heated is shielded from contact with the flames and the products of combustion; a furnace in which the heat is applied to the outside of the chamber containing the charge.
= reheating furnace.
A portable furnace used by plumbers to melt lead, for soldering, etc.
A furnace used for reducing metal ore to the uncompounded metal.
A furnace used to reheat iron or steel prior to hot working.
An electric furnace in which the heat is generated by the passage of a current through conductors of high resistance.
A furnace which uses an electric arc as a heat source, especially for steel-making
A furnace in which the roof and walls are heated by flames and radiate heat on to material in the centre of the furnace
A furnace in which the charge is moved forward on driven rollers.
An induction furnace in which a high-frequency electric current is used.
A cylindrical furnace for refining metals, with openings at the bottom for blowing in air and originally with a dome leading to a chimney above
