Boiler Gas Valve Problems And Faults - Heating | Gas
May 01, 2000 · Any tightly tuned boiler (10% excess air or less) without oxygen trim will experience incomplete combustion when receiving the LNG/natural gas mix, but they may not know or discover it. Some years ago, during startup of a boiler converted to gas, the operation resulted in tripping another recently converted boiler because of low gas pressure.
Fuel trains regulate the amount and the pressure of gas to burners. They also keep gas out of the combustion chamber whenever equipment is shut off. This is accomplished with a series of regulators, flow control valves, and special shutoff valves. The special automatic shutoff valves are designed for low leakage and are spring loaded to close.
