Take your Hg CEMS Data and Plot it out.
Check it against things like:
Things are related in ways that have not yet been fully investigated.- Research will continue.

Plant Load    CO/CO2    NOxSO2  We did not find a relationship with Hg vs. Megawatts- it is more related to firing rate, carbon-in-ash, Excess O2, etc-
COMBUSTION.
Hg changes when other conditions change and we don’t always know why.

Though it looks like we can track HgT by following any of the parameters shown, I feel that each item shown is a secondary effect and not indicative of HgT.  Each is actually following MW load and I feel it is something related to MW load that HgT is following - mainly carbon in the ash.  I think we need to state something about further analysis of data is needed because we only just completed the RATA a week ago.

I feel kind of strong (to myself) that a lot of the mercury variation is due to carbon variation which is directly related to boiler fire variability.  Once I track actual fire quality vs. HgT, I think we'll know more about the fluctuations of HgT and fire quality.
