The 50% base load CO levels are between 215 and 250 vppm. This graph also shows a wider ambient temperature range. As stated on the phone today the 45 vppm NOx levels are achievable across the entire operating range. I apologize for the SI units on the graph, but I ran out of time to convert the chart to imperial units, but hopefully it helps for you to understand the concept. Call me at home this weekend, if you need anything. -- John A. March, P.E. Market Manager Rolls-Royce Energy Systems, Inc. 105 North Sandusky Street Mount Vernon, Ohio 43050 U.S.A.
