The boiler already has an FGD system so that biological treatment for nitrogen removal from the wastewater will be used. The same SCR system will be used on a new 700 MW coal-fired boiler. In the U.S., the EPA has awarded two contracts for pilot scale (about 0.5 MW) investigations of two NOx removal processes by catalytic reduction with am- monia.
