While the gas from these sources has a similar analysis, it is not entirely the same. The auto-ignition temperatures of hydrogen and natural gas are very similar.

The lower the ignition temperature, the more dangerous the gas. For 70% Propane and 30% Butane at 20 degrees Celsius the pressure is 102 PSI (lb/sq.in.) In your case (195 psig), the auto-ignition temperature would remain near about the same temperature … ignition temperature for natural gas is higher than gasoline and diesel fuel. Gas ignited in a confined location can be. It has an autoignition temperature of 580 C or 1076 F. So a piezo must produce a spark temperature greater than 580 C or 1076 F. 1 2.

The gas supplied to Enbridge Gas comes from western Canada, the United States and Ontario producers. Natural gas is lighter than air and disperses into the atmosphere.

While working with natural gas, keep natural gas away from ignition sources, such as heat, sparks, and open flames. This is a list of flame temperatures for various common fuels.

Gasoline and diesel fuel will pool on the ground, increasing the danger of fire.

Gas Ignition Temperature Classification in ATEX and IECEx Hazardous Areas Explosive gases can auto‐ignite in air, without a spark or flame present, if they become hot enough. Natural gas is lighter than air, approximately 1/2 the weight, and will dissipate if allowed to reach the outside atmosphere.

Ignition Temperature Range 1000 -1200 °F . Spontaneous ignition of compressed hydrocarbon gases is also generally less likely, given the much lower turbulent blow-off velocity of hydrocarbons in comparison to that for hydrogen. Natural gas in the broad sense is a gaseous material consisting primarily of methane and deriving from one of three main types of sources: deeply buried fossil fuels; non-fossil organic material decayed by anaerobic bacteria; and coal converted through a chemical process. Each cubic foot of natural gas requires 10 cubic feet of air for proper combustion (the ten cubic feet of air has 2 cubic feet of oxygen, and the rest is mostly nitrogen-i.e air is … Natural gas is a naturally occurring gas mixture, consisting mainly of methane. Minimum Ignition Current ratio The minimum current required from an inductive spark discharge to ignite the MOST EASILY IGNITABLE MIXTURE of a GAS, MIST or DUST in air .....relative to that which is required to ignite a METHANE-AIR mixture .

Such gas release operations should only be performed in well-ventilated areas or by safely venting the contents of gas lines and equipment to the outside atmosphere away from people, animals, structures and sources of ignition.

Adiabatic flame temperatures for common gases are provided for air and oxygen.

Also, take precautionary measures against static discharge; for example, do not use a cell phone or other Auto-ignition tmperature does tend to decrease with increase in pressure but not appreciably. The automatic ignition temperature for methane, or natural gas, is 1076 degrees Fahrenheit. Natural gas is non-toxic and will not contaminate groundwater if spilled. ...
