Note:

Gas turbine and duct burner NOx, CO, and UHC emissions rates

are computed from user-specified concentrations, input on the Environment topic.

NH3 emissions are user-specified via the 'Ammonia slip' input on the SCR design menu.

The program DOES NOT predict emissions of these compounds.

It is the user's responsibility to input OEM-provided

data that is consistent with equipment operation at this specific running condition.
