Gas Train Components

Gas trains are the piping, valves, regulators, and components in the fuel delivery system (fuel train) just prior to any burner. They are controlled by burner management and combustion control systems and they are typically natural gas but they can be other fuels as well, such as propane, landfill, methane, sewer gas, or some other type of bio-gas product. Most systems use a separate smaller (pilot) train to establish a pilot flame before igniting the main flame.

Gas trains vary from burner to burner based on capacity, fuel type, available gas pressure, voltage, and insurance requirements.
