natural gas orifice vs propane

If you are installing a new gas stove or BBQ, you may be wondering what the difference is between natural gas orifices and propane orifices. Both types of orifices are designed to provide a specific amount of gas flow to your appliance, but they are not interchangeable. In this blog post, we will take a closer look at the unique differences between natural gas orifices and propane orifices so that you can make the best decision for your needs.

Natural Gas Orifice Vs Propane Orifices: What’s the Difference?

  • Natural gas and propane have different properties which require different types of orifices. Natural gas is definitely lighter thanthe normal air, while propane is more heavier than air. This means that the natural gas will rise in the event of a leak while propane will sink. For this reason, it is critical that you use the correct type of orifice for your appliance.
  • Another difference between natural gas and propane is the BTU (British thermal unit). Natural gas has an average BTU of 1,030, while propane has an average BTU of 2,500. This means that propane burns hotter than natural gas. As a natural gas orifice vs propane result, propane appliances require a smaller orifice than natural gas appliances. If you were to use a natural gas orifice on a propane appliance, the appliance would not receive enough fuel and would not function properly.
  • It is also important to note that natural gas orifices are larger than propane orifices. This is because natural gas has a lower pressure than propane. Natural gas appliances are designed to operate at a lower pressure, while propane appliances are designed to operate at a higher pressure. If you were to use a propane orifice on a natural gas appliance, the appliance would receive too much fuel and could be dangerous.
  • Now that we’ve looked at the difference between natural gas and propane orifices let’s take a closer look at each type of orifice. Natural Gas OrificesNatural gas orifices are made of brass and have a tapered design. The Orifice size is determined by the BTU of the appliance. Natural gas orifices are available in a variety of sizes, from 0.020 inches to 0.100 inches.
  • 0.050 inches is the most popular size for natural gas orifices. Propane OrificesPropane orifices, which are made of stainless steel, have a non-tapered design and come in a few different sizes that are determined by the BTU of the appliance they’re being used with.
  • The last major difference between natural gas and propane is pressure. Natural gas is typically delivered to homes at around 0.5 psi, while propane is delivered at around ten psi. Because of this difference in pressure, natural gas appliances typically have larger orifices than propane appliances.

Conclusion

Now that you know the difference between natural gas orifices and propane orifices, you can make sure that you purchase the correct type of orifice for your needs. Be sure to take note of the BTU rating of your appliance and either measure the existing orifice diameter or consult your owner’s manual before making a purchase so that you can be sure to get the right size.
