Natural Gas Fuel Piping System

Illustration 4 - Gas Train Components

1. Install a controlling gas regulator in the main gas line within 25 feet of the burner.
a. This regulator should be sized to provide the required gas flow at the inlet of the burner manifold.
b. 3 – 5 psig is the nominal expected gas pressure required at the burner Consult the burner profile
sheet found on the plant flash drive for more precise information. ( See Detailed Burner
Performance Sheets)
c. Exact gas pressure must be set at the initial start-up depending on piping configuration, burner
size, and maximum rated capacity.
2. The piping from the gas regulator outlet to the burner gas manifold should be sized to minimize
pressure losses.
3. The pipe size from the control regulator to the gas train, can be identical to the gas pipe size at the
entrance to the burner gas train, see tables below.
NOTE:
It is normal for the regulator size to be smaller than the line size.
