This application uses a Vortex HDPV2 Gate to discharge batches of dry calcium carbide from one pressurized holding vessel into another. The batch is then fed into a reactor, where it is mixed with water to produce acetylene gas. Calcium carbide and acetylene gas react with one another to create oxyacetylene gas. Especially in the fabrication industry, oxyacetylene gas is used to fuel a very high temperature flame, which allows them to weld and cut metal.
