Propane (LP) orifice sizes typically vary from 0.010 to 0.016′′ diameter, but 0.010′′ appears common, for which energy con- sumption is 548 Btu/hr at a typical 11′′ pressure.

Divide the flow of the liquid by the velocity of the liquid to determine the area of the orifice in square feet. In the above example, you would divide 8 by 2. The total area of the orifice would be 4 square feet.

Natural gas orifices are larger than propane, to allow extra fuel to flow through at lower pressure. Propane orifices are smaller, to account for the higher pressure and increased energy output.

What is the difference between a natural gas orifice and a propane orifice? Natural gas is fed at a smaller pressure than propane, so to get the same heating value (usually measured in BTUs), a natural gas orifice has to be smaller than a propane one.

You can tell by the way the flames look on the stove. If the flames are longer than 3 inches and yellow/red on the ends, that means you’re unit is set up for natural gas. If the flames are 1-2 inches long and mostly blue with yellow flickers and tips, then it’s set up for propane.

Most stoves come set up ready for natural gas because it is the most commonly used fuel for indoor cooking. But if your stove is powered by electricity, you’ll need to convert to a natural gas powered stove before having it fueled by propane.

Bottom line: there is NO performance difference between propane and natural gas unless you’re grilling in the arctic. The only major difference is the convenience of natural gas and never running out of fuel. Your choice ultimately boils down to which fuel sources you have access to and the costs in your area.

Propane is usually more expensive than natural gas, but the same amount produces about twice as much heat. In some areas, natural gas is more economical, and in others, propane costs less. Both types of fuel are more efficient and less expensive than electricity in many regions.

Q: Is it healthier to grill with propane or charcoal? A: Props go to propane. In one study by scientists, charcoal-grilled meats contained more carcinogens called polycyclic aromatic hydrocarbons (PAHs) than meat heated with propane. Propane still produces some PAHs and HCAs, though, so take these steps with any grill.

The source of a gas odor could be inside your home from a leak in your house line or appliance connection. It could also be outside from leaks in a service or main line that could come into your home through foundation walls or drain lines. Natural gas pipelines have a proven record of safety.

Even if propane is not ignited, the buildup of the gas can be deadly due to inhalation. Breathing the gas can cause hypoxia, which is a form of oxygen deprivation that can lead to death.

If you smell gas, inside or outside of your home, immediately take these steps:

1. Extinguish flames and sparks. Put out all smoking materials and other open flames.
2. Leave the area.
3. Shut off the gas.
4. Report the leak.
5. Do not return to the building or area.
6. Get your system checked.

You would smell the gas coming from the vent of the regulator. 4) If your regulator was underwater for any reason it should be changed out. When a regulator goes underwater, debris and/or chemicals can get inside the regulator spring area. This can cause the spring to corrode and fail.

Propane is explosive and propane can explode but a propane-LPG tank explosion is actually very rare. Propane tanks (gas cylinders) can explode but not easily or often. It is actually really hard to have a propane tank explode.

Serious safety hazards, including fire or explosion, can result. If an appliance valve or a gas line is left open when the propane supply runs out, a leak could occur when the system is recharged with propane. If your propane tank runs out of gas, any pilot lights on your appliances will go out.

While your tank should not be stored indoors, it should also not be stored in direct sunlight. On a hot sunny day, the temperature of a tank that’s not properly stored could quickly go above 120°F. The hotter your tank gets, the greater the pressure will be inside the tank.

In hot weather, the tank needs to be placed in a place that does not exceed 120 Fahrenheit. At -44 degrees F or lower, propane stays as a liquid, there is little vapor and propane appliances won’t function properly. If flames or a source of ignition is present, the propane will ignite resulting in an explosion.

Propane tanks do not just explode if they fall over, are hit by the lawnmower or a car. If your propane tank is left or stored in your vehicle, heat, sunlight and motion can increase pressure to an unsafe level creating a flammable, explosive environment. All new tanks must be properly purged before the first filling.

The Flash Point of propane is -156 degrees Fahrenheit. This is the temperature at which already ignited propane will continue to burn on its own. If the temperature drops to -157 degrees, propane will extinguish itself – unless there’s a continuous source of ignition present.

Storing propane tanks outdoors is perfectly safe, but it’s best to choose a spot that’s away from your home. Storing propane tanks in the summer is easy, too. In warm weather your propane tank can still be stored outdoors on a flat, solid surface.

Nothing will happen, if the tank is connected to the grill and the tank valve is left turned on, unless one or more of the burner control vales isn’t turned fully off or is leaking. In that case, propane from the tank will escape through the burner(s).

Consider the following consequences of letting your propane tank run out: If a valve or gas line is open when the propane supply runs out, a leak can occur when the system is recharged with propane. Air and moisture that penetrates an empty tank can cause rust build-up inside the tank.

Propane grills are VERY safe when used properly, but can explode due to a gas valve being left on causing gas build-up later ignited by a flame. Also, temperatures over 160° can increase pressure inside the tank & exceed the tank’s safety release valve’s capacity & lead to explosion.

Whenever the gas valve is left ON, the gas buildup can occur. This is not dangerous when the natural gas grill is turned off, but it can lead to an explosion whenever the flame on the grill is ignited. “Likewise, leaving the valve open can cause gas leaks.
