Benefits:

• Reduces the incidence of tube overheating, flame impingement and O2 /CO imbalances.
• Balances average fuel flows to within +/- 5% of mean.
• Offers more uniform temperature profiles.
• Decreases excess air levels.
• Lowers fuel costs.
• Allows NOx reductions as high as 24%.

How it works:
Test ports are installed on the gas piping system to each burner and at other preselected points in the gas piping system. A single, highly accurate pressure measurement instrument (National Bureau of Standards) is used to record pressures at each test point. Then a computerized nodal network analysis is performed to develop correct orifice sizing for each burner to balance gas flow.
