LNG: Liquefied Natural Gas

CNG: High Pressure Natural Gas

Comparison of ignition points.

Diesel fuel: ignition point 220℃; gasoline ignition point 427℃. But gasoline is volatile, gasoline vapor to diesel fuel ignition point is low.

Liquefied Petroleum Gas (LPG):ignition point 490℃.

Natural gas: ignition point 650 ℃.

Gas: gas mixture, ignition point greater than 500 ℃.

Specific gravity comparison.

Liquefied Petroleum Gas (LPG):Specific gravity 1.5-2 with air, which is deposited downward in case of leakage and is prone to the safety hazard of explosion.

Natural gas (NG): specific gravity of 0.58-0.79 with air, will quickly evaporate into the air when a leak occurs, not easy to cause safety hazards.

Explosion limit comparison.

Liquefied Petroleum Gas (LPG): 1.7% -9.7%. Very easy to explode.

Natural gas (NG): 5-15% of the explosion limit. Not prone to explosion.

From the above, we can see that all safety indicators of natural gas are higher than those of several common fuels, so the safety of using natural gas as fuel is higher compared to other fuels.
