Bunsen burner, prem, lpg 11mm
Our Premium Range burners are constructed using a heavy pressure diecast base, which is finished in a chemically resistant blue acrylic paint and nickel plated brass chimneys. All burners are factory tested for flame quality and leakage before packing, using the standard gas pressure and specifi ed gas type for each burner. Base diameter: 80mm. Natural Gas Burners Typical flame temperatures with the air inlet open (‘blue fl ame’) will be 900 to 1000°C. This temperature is achieved at the tip of the blue fl ame. Typically the flame temperature with the air hole closed (‘yellow flame’) will be 750 to 800°C. A yellow flame is not only cooler but also ‘dirtier’ than a blue flame and is likely to coat heated objects with a black Carbon deposit. The temperatures achieved depend on the mains gas pressure and chemical composition of the gas. Standard mains gas pressure in the UK is 20 millibars (mb). LPG Burners These burners are designed to be used with Propane (at a gas pressure of 35mb) or Butane (at a gas pressure of 28mb). The appropriate pressure reduction valve must be fi tted to gas cylinders or tanks. Typically, the flame temperatures reached (with air inlet fully open) are rather less than those achieved when using natural gas, being in the range 850 to 950°C. Due to the nature of L.P.G. gases, all L.P.G. burner jets are sealed with a jointing compound to prevent leakage. If for any reason a burner jet has to be replaced, a jointing compound MUST be used.
