Boiler Combustion | CleanBoiler.org

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

Temperature Considerations for Pressure Relief Valve Application - National Board of Boiler …

A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. This valve would have a stamped set pressure of 500 psig and a CDTP of
