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) ...

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 ...

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 ...
