Selective catalytic reduction (SCR) for NO x removal from utility boilers has been shown to have extremely high removal efficiencies. In recent years, there has been increased focus on a potentially ...

Commercially available technologies for reducing nitrogen oxide (NO x) emissions from coal-fired boilers are enabling industry compliance with today’s regulatory requirements. Low-NO x burners (LNB) ...

SCRs (silicon-controlled rectifiers), or thyristors, have higher current and voltage ratings, lower conduction losses, and more robustness than triacs. For these reasons, SCRs are better suited to ...

This standard will address the control functions associated with the selective catalytic reduction systems on fossil fired steam boilers greater than 200,000 lbs/hr and combustion turbines greater ...
