What size orifice is needed for natural gas?
What size orifice is needed for natural gas?
Propane and Natural Gas Are Supplied at Different Pressures Cooktop burners typically supply about 40,000 BTUs per hour. A propane stove orifice size is about 0.082 inches (drill size 45), but the valve on a similar stove that uses natural gas needs an orifice that is almost 0.125 inches (drill size 35).
Is natural gas orifice bigger or smaller?
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.
Can you drill out propane orifice natural gas?
Converting from LP to natural gas safely and correctly involves more than might be apparent to the typical DIYer. Frankly, it’s folly to drill out orifices. If you can get the correct orifice, don’t do it.
Can I use natural gas orifice for propane?
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. This suggests that you can convert a natural gas appliance to a propane one and vice versa by changing the orifice on the gas valve.
Can I get natural gas in a tank?
Natural gas is not stored in household tanks because the symmetry of its molecule makes it hard to liquify. You could store methane in a tank in the gas state but it has such low density in the gas state that you could not store a usable amount.
What size is a LP gas orifice?
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.
Can you drill out a propane orifice?
Can I use Propane orifice for natural gas?
Gas types are not interchangeable. Natural Gas orifices will have a larger hole as it is a lower pressure gas and Propane is a compressed gas and the orifices will have a smaller hole. They are not interchangeable. You never want to use an orifice that is drilled for Natural Gas on Propane or Propane for Natural Gas.
What is a natural gas orifice?
Orifices are responsible for the amount of gas that flows into the burners. Orifices are brass fittings that screw into (spud) or onto (hood) valves. These orifices will have various hole sizes as they determine the gas type either Propane or Natural Gas.
Where can I get a gas orifice drill table?

What sizes of orifices correspond to grills and drill sizes?
– TheGrillFather.com What sizes of orifices correspond to grills and drill sizes? There is very little information anywhere on what sizes orifices are for what grills – All Sizes are in Drill numbers and in MM or Millimeters, the small the number of the drill, the Larger the hole.
How to drill the gas orifice from propane to natural gas?
Before I wasted money and bought the natural gas orifice from williams brewing, I wasn’t sure what part I was supposed to drill. I made this video to help you guys out if you were in the same boat as me. Works like a champ, great blue flame on 3 burners at the same time. Loading…
Is it folly to drill out an orifice?
Frankly, it’s folly to drill out orifices. If you can get the correct orifice, don’t do it. You need to get the correct sized orifice, get the gas pressure correct which may involve a new regulator, adjust the primary air shutters correctly and generally be able to look at the equipment and how it’s operating to be sure it’s correct.
How big of an orifice do you need to measure natural gas?
When sizing, consider using 100 inches instead of 50 inches; 200inches instead of 100 inches but be careful! Note that AGA -3 Appendix- 2-F provides guidelines for using high differential for flow measurement of natural gas. This maximum limit is dependent upon the thickness of the Orifice Plate, diameter and beta ratio.
How big is an orifice on a propane stove?
A propane stove orifice size is about 0.082 inches (drill size 45), but the valve on a similar stove that uses natural gas needs an orifice that is almost 0.125 inches (drill size 35). If you want to convert from one to the other, you can replace the cap on the gas valve with one that has the correct orifice, but that’s only part of the process.
How big is the orifice in a BBQ Grill?
For instance, if we have a barbecue that is designed such that each burner is getting 12,000 BTU’s of gas flowing through each orifice in the tip of each control valve we can look at the chart above and see that as the regulator pressure gets lower the size of the hole in the orifice gets bigger.
Where can I find data on propane orifices?
Similarly, you can find the same data for propane by consulting a propane orifice size chart. If you’re considering converting between natural gas and propane, you can look up the combined data for both natural gas and propane on a natural gas propane conversion chart.
