Project Summary
The project involved the design and installation of environmental upgrades for the San Juan Generating Station including new low nitrogen oxides (NOx) burners with overfire air (OFA) to reduce NOx formation in the boilers, the addition of powdered activated carbon (PAC) injection to reduce mercury emissions, coupled with new pulse jet fabric filters for enhanced control of particulate emissions. A chemical additive system to improve sulfur dioxide (SO2) removal for the wet flue gas desulfurization absorbers was also included in the project scope.
