Systems to Control Nitrogen Oxides in Coal Fired Power Plants

Commonly referred to as NOx, Nitrogen oxides are one of the primary pollutants emitted by high temperature combustion systemssuch as pulverized coal (PC) fired boilers. Due to its role in both acid rain and ozone formation, NOx is a regulated pollutant under the EPA’s Clean Air Act. The options to reduce NOx emissions include source reduction and post combustion treatment of the flue gas. To control NOx at source, fuel and air distribution, otherwise referred to as staging, are modified to reduce flame temperatures…Read More
