fuel bound nitrogen in ULSD

[Stephen Little]

Ohio University is planning to purchase two dual fuel boilers and use highway spec ULSD for the oil.

The problem is that highway ULSD does not seem to be rated nor tested for fuel bound nitrogen. ULSD should be very low in FBN, but how low is the question....and will is stay that way. Some oils companies are adding nitrogen back in.

I would appreciate hearing from anybody who burns ULSD in their boilers regarding:

• Do you use a special spec or just purchase highway ULSD
• How is FBN specified...or not
  
• What your emissions test results were, especially for NOx and PM2.5
