C3H8 - The molecular makeup of propane consists of 3 Carbon molecules and 8 Hydrogen molecules
Propane Boiling Point -44°F
Weight of 1 Gallon Liquid Propane*4.24 Lbs
BTU per Gallon of Propane Gas*91,547 so about a gallon every 3 hours for a 30k furnance
BTU per Lb. of Propane Gas 21,591
BTU per Cu Ft of Propane Gas*21,591
Propane Properties Explained
Propane Boiling Point - Water boils at 212°F meaning that it becomes a gas at this temperature whereas water is still a liquid at 200°F. Propane is a liquid at -50°F and boils at -44°F. In other words, at 10 degrees below zero, propane is well past its boiling point.
It means that propane is cold enough freeze your skin (and tissue underneath) to the point of severe damage.
Specific Gravity of Propane Gas - One cubic foot of propane weighs .1162 lbs. and one cubic foot of air weighs .07655. Dividing .1162 by .07655 equals 1.52. What does this mean? Propane is heavier than air and will seek the lowest space available.
Specific Gravity of Liquid Propane - One gallon of propane weighs 4.24 lbs. One gallon of water weighs 8.33 lbs. Dividing 4.24 by 8.33 equals .51. This means propane is less dense than water (lighter than water) and will not sink in water, so to speak.
BTU - As defined, a British Thermal Unit is the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It takes about 143 BTU, or .0016 gallons of propane, to melt one pound of ice (at 32°F).
About .33 gallons to make 30000 BTU
Ignition Temperature in Air 920-1020°F
Maximum Flame Temperature 3595°F
Octane Number Over 100
HD5 grade propane is "consumer grade" propane and is the most widely sold and distributed grade of propane in the U.S. market. HD5 is the highest grade propane available to consumers in the United States and is what propane companies ordinarily sell to their customers. HD5 spec propane consists of:
Minimum of 90% propane
Maximum of 5% propylene - propylene is used in the manufacture of plastics
Other gases constitute the remainder (iso-butane, butane, methane, etc.)
A good burn for propane is 90 plus percent efficient and rest of energy makes water.
C3H8 +5O2 --> 3CO2 + 4H2O + heat So a convection heater will dump a lot of moisture if vented into the trailer.
The gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
With complete combustion, an LPG (Propane) flame burns at a temperature of around 1,980°C.
A bad burn for propane is
A yellow color is due to incandescence of very fine soot particles that are produced in the flame at around 1000 degrees C
This type of flame only burns at around 1,000 °C.
Propane + Oxygen → Carbon Dioxide + Carbon Monoxide + Water + Heat
2 C3H8 + 9 O2 → 4 CO2 + 2 CO + 8 H2O + heat
If the room fills with 1.28% CO a typical human will pass out in 2-3 minutes
