Page "Forge" Paragraph 20

A gas forge typically uses propane or natural gas as the fuel.

One common, efficient design uses a cylindrical forge chamber and a burner tube mounted at a right angle to the body.

The chamber is typically lined with refractory materials, preferably a hard castable refractory ceramic.

The burner mixes fuel and air which are ignited at the tip, which protrudes a short way into the chamber lining.

The air pressure, and therefore heat, can be increased with a mechanical blower or by taking advantage of the Venturi effect.
