Abstract
A gas carburizing furnace wherein the liquid organic composition is introduced into the furnace through a perforated container contained therein. The perforated container comprises a thermal plate at the bottom and perforated walls made from a catalytic material. Therefore, the liquid organic composition entering the container through the dropping port is vaporized when it comes in contact with the hot thermal plate and is cracked while passing through the perforations in the catalytic material.
