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.
