process. The primary measurements required under the Boiler Area Source Rule are flue gas oxygen content and flue gas carbon monoxide content at the high-fire or typical operation load. a) Examine the combustion control components (i.e., the system controlling the air-to-fuel ratio) and ensure it is functioning properly.

Jul 21, 2010 · In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas.
