What is the complete combustion of propane?

The ideal combustion ration (“complete combustion”) for propane is 1 part propane (4\%) to 24 parts of air (96\%). Even at this ideal ration, combustion products, known as flue gases, still occur. However, under this scenario, those products are harmless carbon dioxide and water.

What is the flammable range for propane?

Liquid propane is stored in tanks and vaporizes when it is released from the tank because propane vaporizes at any temperature above -44°F. The flammability range of propane is approximately 2 – 10 percent propane in air.

Why do we need more air for combustion for propane?

When not enough oxygen is present for complete combustion, incomplete combustion occurs when propane burns and forms water, carbon monoxide, carbon dioxide,and carbon. Unlike natural gas, propane is heavier than air (1.5 times as dense). These bonds also cause propane toburn with a visible flame.

Is propane flammable or combustible?

What is important is that propane is not a flammable liquid. It is a flammable, liquefied gas. This difference is very important and the reason that the two must not be stored improperly.

What is the combustion of propane used for?

Propane is a flammable hydrocarbon gas that is liquefied through pressurisation and commonly used for fuel in heating, cooking, hot water and vehicles. Propane can also be used for refrigerants, aerosol propellants and petrochemical feedstock.

Is the combustion of propane spontaneous?

The combustion of propane is highly spontaneous at all temperatures.

Which concentration of propane in air is combustible?

2.2 to 9.5 \%
A typical gas, such as propane, has flammability/explosive limits in air of 2.2 to 9.5 \% by volume. [Matheson Gas Data Book, 6th Ed.], so any propane/air mixture in this range is flammable and so is potentially explosive.

Is propane more explosive than gasoline?

Propane causes a higher explosive risk when it is released This creates a much more dangerous explosion risk. Natural gas goes up in the air when it is released so it scatters more quickly, lowering the chance of an explosion.

What is the air to gas ratio for propane?

Stoichiometric air-fuel ratios of common fuels

Fuel	By mass	By volume
Propane (LP)	15.5 : 1	23.9 : 1
Ethanol	9 : 1	—
Methanol	6.4 : 1	—
Hydrogen	34 : 1	2.39 : 1

How much does propane expand when ignited?

Propane expands at 1.5\% per 10 °F.

Is propane heavier than air?

As mentioned above, since propane gas is heavier than air, it will settle to the lowest possible level while also dissipating into the atmosphere.
