And in some parts of the country like California, Texas, Louisiana and New Jersey, boiler operators are required to achieve and maintain even more stringent air quality emission standards of ultra low NOx levels (ULN), typically less than 10-12 ppm and as low as single digit NOx levels 5-7 ppm of NOx.
Low-water cutoff: It is a mechanical means (usually a float switch) or an electrode with a safety switch that is used to turn off the burner or shut off fuel to the boiler to prevent it from running once the water goes below a certain point. If a boiler is "dry-fired" (burned without water in it) it can cause rupture or catastrophic failure.
Today's ultra low NOx boilers use advanced technology and methods to reduce NOx emissions. Low NOx burners are designed to control air and fuel mixing at each burner, which creates more branched and larger flames.
Air pollution control regulations may require that these burners be either replaced or made cleaner and more efficient. Improved performance may be possible by retrofitting these small conventional boilers with high-efficiency, low nitrogen oxide (NO sub x) dual-fuel burners in the 4 to 30 million Btu per hour (MBtu/h) firing range.
Boilers and process heaters emit air contaminants including oxides of nitrogen, carbon monoxide, volatile organic compounds, oxides of sulfur, particulate matter and toxic air contaminants. All boilers and process heaters with a maximum heat input equal to or greater than 5 million Btu per hour (MMBtu/hr) require a permit to operate from the

Nitrogen filled vessel. it will be extremely hard to get to 100% N 2 in any vessel or tank. If the vessel is capable of weeing an external pressure of 15 psig the one would pull a vacuum and introduce N 2 to 1 psig. This is would have to repeated several times to get the purest N 2. To do this one has to use dry N 2.
