Tests were completed at the Duke Power Cliffside Steam Station on the Unit 5 SCR system to increase NOx removal from an initial design value of 85% to an in-use operating level of 93%. These tests took place from May 24 to May 26, 2004 at the start of the third OTAG season for the SCR that was furnished by Riley Power, Inc., a Babcock Power Inc. company. Unit 5 is a balanced draft, subcritical boiler that operates at 590 MW firing eastern bituminous coal. Two SCR reactors are installed at the economizer outlet of the boiler including economizer bypasses for low load operation. Anhydrous ammonia is the reagent for NOx reduction. Each reactor had two initial catalyst layers when the unit was tested.
