Propane:

Propane is utilized regularly for oxygen cutting in a number of plants due to its availability and its much higher overall heat value (Mj/m3) than natural gas. For appropriate combustion throughout cutting, propane requires 4 to 4.5 times its volume of preheat oxygen. This requirement is offset somewhat by its higher heat value. This is stored in liquid form and it is easily transported to the work site.

Propylene

Propylene, under various different brand names, is utilized as fuel gas for oxygen cutting. One volume of propylene needs 2.6 volumes of torch supplied oxygen for a neutral flame and 3.6 volumes for maximum flame temperature. Cutting tips are same to those utilized for MPS.
