Safety controls for any fuel gas fired boiler
Low Natural Gas Pressure: A pressure switch in the natural gas line stops the burner if the gas pressure gets too low. If the natural gas pressure falls too low, the burner could go out. If natural gas is still flowing, a combustible mixture could fill the boiler combustion chamber (explosion hazard). Low Flame Strength: A flame detector stops the burner if the flame becomes weak or goes out.

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.

How is NOx Formed | CleanBoiler.org - Boiler Consortium
How is NOx Formed. In industrial boilers, NOx is primarily formed in two ways: thermal NOx; fuel NOx . Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils.

Boiler Combustion | CleanBoiler.org
One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 oils have been achieved.
