What determines the size of the orifice in a gas distribution system?

The size of the orifice in a gas distribution system is determined primarily by the fuel type and the distribution needs. Different types of fuel, such as natural gas or propane, have varying physical properties that influence combustion efficiency and performance. The orifice size is critical for ensuring that the correct gas volume and pressure are delivered for optimal burner operation.

When designing a gas distribution system, it is essential to match the orifice size to the specific fuel type being used and the requirements of the appliance, including its heating capacity and intended application. This ensures proper combustion, minimizes safety risks, and maximizes energy efficiency.

Understanding the relationship between fuel type and the orifice size helps installers and engineers make informed decisions that adhere to safety standards and performance expectations, underscoring the importance of this aspect in gas system design.
