Acetylene gas supply device for vacuum carburizing furnace and its supply method

摘要

To provide a feeding device of acetylene gas for a vacuum carburization furnace that has a simple and inexpensive structure and feeds high-purity acetylene gas to a vacuum carburization furnace regardless of gas feed pressure of an acetylene container.SOLUTION: A feeding device 1 of acetylene gas for a vacuum carburization furnace includes an acetylene container 11 filled with acetylene dissolving in a solvent, an acetylene feeding route 16 for feeding acetylene gas from the acetylene container 11 to a vacuum carburization furnace 200, a heat exchanger 13 installed in the acetylene feeding route 16 for liquefying a solvent component included in the acetylene gas, and a gas-liquid separator 14 installed downstream of the heat exchanger 13 in the acetylene feeding route 16 for separating the liquefied solvent and the acetylene gas rid of the solvent component.SELECTED DRAWING: Figure 1
