What is a propane gas orifice?
Orifices for Valves 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.
What is the purpose a gas orifice?
The gas orifice dispenses fuel into the combustion or burner tube through a small, high precision hole. The orifice delivers just the right amount of fuel to mix with the correct amount of air, to create just the right flame for the job in your appliance.
What is the difference in orifice between natural gas and propane?
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).
What is the orifice size for propane?
0.010 to 0.016′′
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.
Which is bigger orifice propane or natural gas?
The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure. In this case, the higher pressure gas flowing through a larger orifice will result in more gas through the burner and likely, more flame…an unnecessarily large flame.
Can I use natural gas orifice for propane?
They are not interchangeable. You never want to use an orifice that is drilled for Natural Gas on Propane or Propane for Natural Gas. Using a Natural Gas orifice on a Propane grill will produce an abnormally large flame due to too much gas flowing through the hole and can be extremely dangerous.
What orifice is bigger propane or natural gas?
What does orifice size mean?
The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine. This causes the pressure to increase. Choosing a nozzle with too large of an orifice will reduce operating pressure.
Is a Propane orifice smaller than natural gas?
Can I convert any propane grill to natural gas?
For less than $100 (usually), you may be able to replace the valves and burners on a propane grill and adapt it to burning natural gas. However, these conversion kits are often after-market products made by third-party manufacturers, and some grill manufacturers expressly warn against conversion.
Is propane orifice bigger or smaller than natural gas?
