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
