What size hole is a propane orifice?
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 natural gas?
The size of natural gas pilot orifices normally ranges from around 0.014 to 0.026 inches (inches diameter). For example, 0.026′′ for a commercial cooking appliance pilot (1,835 Btu/hr at 4′′ pressure) and 0.018′′ for a natural gas water heater pilot (879 Btu/hr at 4′′ pressure) are both acceptable values.
What happens if you use a natural gas orifice with propane?
Running propane through an orifice designed for natural gas and lower pressure will result in an overly large flame and soot. The flame will be bigger and may cause damage and even an explosion. This is because the orifice jet designed for natural gas is larger than the one for propane.
Is a propane orifice bigger than a natural gas orifice?
Because of gas service pressure, natural gas orifices are larger than propane ones. Attempting to use a propane appliance with natural gas will likely result in a very small flame or no burner flame because of the lower pressure gas and the smaller orifice.
How do you size an orifice?
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.
Which orifice is larger 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.
