Where are the gases mixed in a two-barrel torch?

• A. In the lower tube
• B. In the mixing chamber near the nozzle
• C. In the gas cylinders
• D. In the upper tube

Answer: (A)

In a two-barrel torch, the two gas streams are fed separately and come together as they travel through the lower tube. The design places the mixing point in that lower section, so the fuel and oxidizer blend before they reach the nozzle and flame. This setup helps control the gas mixture and flame characteristics right before combustion. Mixing in the mixing chamber near the nozzle would describe a different torch design, and mixing in the gas cylinders or in the upper tube doesn’t fit how a two-barrel torch channels the gases.
