In a two-barrel torch, the location where gases mix is the

• A. lower tube
• B. upper tube
• C. torso body
• D. cylinder valve

Answer: (A)

In a two-barrel torch, gases mix where the fuel jet and surrounding air come together in the lower tube. The flow of gas through the lower tube creates a venturi-like effect, drawing air in through openings and mixing it with the gas. This produced fuel–air mixture then travels upward to the nozzle to burn. The upper tube is typically just a conduit for the (already mixed) gas to the flame and isn’t designed as the mixing zone. The torso body isn’t a functional part in the mixing process, and the cylinder valve only controls flow, not the mixing itself.
