Plant Engineering | GAS TECHNOLOGY: Boiler NOx Emissio
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.Get a Quote

How a Low-NOx Burner or Boiler Can Reduce Emissions .
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. By reducing the peak flame temperature, significantly less NOx is formed in the process.Get a Quote
