What is a Burner Orifice?
A burner orifice is a critical component in gas-powered HVAC and heating systems, including furnaces, water heaters, and stoves. It regulates the flow of natural gas or propane into the burner, ensuring proper air-to-fuel mixing for optimal combustion.
The orifice is typically a brass or stainless-steel fitting with a precisely drilled hole. Its size determines the amount of gas that enters the burner. A properly sized orifice ensures efficient heating, reduces energy waste, and minimizes the risk of incomplete combustion, which can produce dangerous carbon monoxide.
Burner orifices vary depending on the type of gas used. Natural gas requires a larger orifice compared to propane, as propane is more energy-dense. When converting a heating system from one fuel type to another, the orifice must be replaced accordingly.
Regular maintenance of burner orifices is essential to prevent clogging from dust, debris, or corrosion. A clogged or improperly sized orifice can lead to poor combustion, reduced heating efficiency, and potential safety hazards.
