Tube Burner Assembly Instructions
Natural Gas or Propane and Compressed Air
The Belchfire Tube Burner Operates with Natural Gas or Propane.
Do not use Acetylene or Oxygen
The BELCHFIRE © Tube Burner uses the 4-F mixer gaseous fuel plus air torch (See 4-F mixer Specifications). The 4-F mixer burns all commercial LP type fuel or natural gas combined with compressed air. No tip or orifice changes are required when changing from one fuel to another. The tube section has evenly spaced tips along its length. The tube length depends on user specifications. A burner of this type allows for more even heat distribution over a given length with adjustable and highly efficient flames. The specially designed tips will operate on pressure as low as 1/4 PSIG. Tube section provided by customer.
The Belchfire Tube Burner now allows a user to heat long sections of material with a single mixer. Belchfire supplies the mixer, tips and tip adapters. The user supplies the tube section. The tube section, square or round, should have a minimum size of 1 1/2″ for welding the adapters to the tube a minimum wall thickness of 1/8″. Weight and ease of handling must be considered when deciding on the tube size. After the tube is cut to desired heating length, drill 1/2″ holes at each tip location. Place the tip adapters in the hole and weld them to the tube. The tip adapters allow the tips to be threaded on to the tube. The mixer requires a 1/2″ NPT female fitting. A hole must be drilled in the end cap or the middle of the tube section to accommodate the fitting. Place the fitting in the hole and weld. For longer tube sections the mixer can be mounted in the middle for a more even distribution of air-gas mixture. The mixer uses Belchfire’s unique technology to increase gas flow to maximize BTU output. End caps now can be welded to the tube. Once all parts are welded to the tube, the mixer and tips can be installed by threading them on. All normal safety precautions associated with this type of equipment should be observed. In addition, check all welding joints for leaks.
The Belchfire tube burner is designed to operate with propane or natural gas plus air supplied by shop air compressor systems.
WARNING: Do not use acetylene or oxygen with these or any other Belchfire torches.
Maximum efficiency will be obtained if air and gas lines are at least 3/8″ I.D.
Gas and air fittings are 3/8″ NPT (Female). Gas line pressure can be 1-15 psi. If regulator is required, use one that is designed for type of fuel being used. Air pressure should be 50-120 psi.
As with all fuel-burning torches, there is a certain amount of hazard involved with the operator and his use of the torch. All normal safety precautions associated with this type of equipment should be observed.
When lighting the tube burner, each tip has to be lit individually.Open gas valve slowly 1/3 turn counter-clockwise. Light the tip closest to mixer first and proceed lighting the next one until all tips have aflame. Once all tips are lit, slowly open air valve counter-clockwise 1/3 turn.
The Belchfire tube burner has a completely flexible flame and can be adjusted to suit any purpose. The size and type of flame is controlled by adjusting the valves.
To shut down -tum gas valve clockwise to stop. Allow air to flow long enough to cool tips. Turn valve clockwise to stop. Shut off fuel and air supply at the source and disconnect the torch.
