Guide to Low-Emission Boiler and Combustion Equipment Selection
4.1.2 Emissions from Existing Steam Generating Units. Boiler owners and operators who need additional generating capacity face a down to regulate the amount of fuel that is allowed to enter the boiler, and the speed at varying characteristics. Prompt NOx can contribute from near zero to more than 100 ppm of NO.
