This standard will address the control functions associated withthe selective catalytic reduction systems on fossil-fired steamboilers greater than 200,000 lbs/hr and combustion turbines greaterthan 25 megawatts. This includes the outlet NOx control usingammonia flow control, startup and shutdown logic, bypass/isolationlogic, dilution air system control, ammonia storage and deliverysystem control, and catalyst cleaning systems. Urea to ammoniasystems are excluded from the scope of this document.
Purpose
The purpose of this standard is to establish the minimum designrequirements for the functional design specifications of selectivecatalytic reduction control systems for use in fossil-fired powerplants.
