Natural Gas and Multi-Fuel Mono Torches
Compare Belchfire gas-only torches for industrial heating applications. Mono torches operate without compressed air. The specifications below distinguish natural gas from other fuels; the required orifice depends on the gas being used.
Review the model details and operating instructions, then select a Mono torch for a quote or ask Belchfire for selection help. For equipment using compressed air, see air-gas Extender torches.
Multi-Fuel Multi-Gas Torches
Belchfire Torches Operate on Natural Gas, Mapp Gas, HPG, LP, Propylene & Propane Gas.
Do Not Use Acetylene or Oxygen

Features:
No Compressed Air Required | Lightweight | Rugged | Simple to Operate
This portable heating torch with high BTU output potential employs a preheating loop for warming and expanding the gas for more combustion efficiency. These torches are not as efficient as the gaseous plus air torches and an orifice change must be made when changing fuels. Minimum gas pressure of 15 psi must be maintained for proper gas to air ratio.
These portable heating torches are lightweight, rugged and flexible in their use. The combustion chamber is a heat resisting material which glows at a bright red. This bright red glow is radiant heat which reflects back into the mixing chamber, thus enhancing the combustion process. Also, the many louvered openings permit a parallel flow of secondary air aiding combustion and reducing noise level.
