LPG Properties

  • LPG is a liquid under pressure but a gas at ambient conditions.
  • Vapour LPG is twice as heavy as Air.
  • Liquid LPG is half as heavy as water.
  • LPG is colorless.
  • LPG has a low boiling point of -18oC.
  • LPG has a narrow flammability range between 1.8 to 9.5% in air.
  • Flash point of LPG is -76oF.
  • The approximate minimum ignition temperature of LPG is in the range 410oC to 580oC. LPG is odourless.
  • Ethyl Mercaptan is added as an odourant to detect LPG in case of leaks.
  • LPG is non-toxic.
  • It is lightly anaesthetic and can cause suffocation, if present in sufficiently high concentrations.
  • Liquid LPG can cause severe cold burns to the skin owing to rapid vapourisation and the consequent lowering of temperature

Advantages of LPG

  • Clean Burning
  • No soot, burners have a longer life - so maintenance is low
  • No spillage as it vaporises at atmospheric temperature and pressure.
  • Effects of corrosion are greatly reduced
  • Instantly controllable flame temperature
  • Avoids Scaling and decarborising of parts
  • Environmentally friendly fuel, with minimal sulphur content and sulphur- free emissions
  • Very high efficiency with direct firing system Instant heat for faster warm-up and cool-down
  • Can be used for a variety of applications
