gas-furnace

Definitions

noun A furnace heated by the combustion of gas.
noun A furnace for distilling gas from coal or some other form of carbon.
noun The name is now applied to many different types of forges, ovens, and furnaces heated by natural gas, water-gas, or generator gas, and used in assaying, annealing, brazing, carbonizing, enameling, forging, japanning, melting, soldering, tempering, or welding metals, and also in warming buildings. Gas-furnaces are named from the work for which they are used: as the an-nealing gas-furnace, the brazing gas-furnace, etc. They consist commonly of a steel frame or box, lined with firebrick or other refractory material, and one or more gas-burners which deliver the gas, mixed with air, under the pressure of an air-blast.
