From Melting Pot Wiki
Overview
A system patented by GTT. The use of a center injector into a surface mix torch.
Principle
The ports are build so that there is an outer layer of oxygen. Then the fuel(2) to be burned is injected out of a half moon port, the moon is made by the center injector being fed through the fuel tube. The center injector being layer(3).
thus triple or tri-mix.
This allows the creation and ability to run a variety of flames and atmospheres.
At the writing of this it is the only oxy/fuel/oxy mixing known. In production.
