Electrostatic precipitators (ESP) particulate matters (PM), Flue Gas Desulphurization (FGD) to control Sox and Low Nox burners with overfire Air
Ports and selective Catalytic Reduction (SCR) system.
The company's nitrogen oxide (NOx) reduction technologies include advanced combustion modification techniques -- such as low NOx burners and overfire air
systems -- and post-combustion NOx control approaches, including NOxOUT and HERT(TM) SNCR systems, as well as systems that incorporate NOxOUT CASCADE, NOxOUT ULTRA, Rich Reagent Injection (RRI) and NOxOUT-SCR processes.

Products include fuel atomizers, aerodynamic flame stabilizers and overfire air
systems, as well as modeling and support services for non-catalytic and catalytic NOx reduction systems for boilers and process heaters.
The burner section was modified to slurry coal clinker burning zone that facilitates optimization of the lower and upper overfire air
into the boiler through four rows of overfire air
ports, two on the front
Combustion air is introduced as either undergrate air (UGA) or overfire air
