What Is Maximum Achieved Efficiency Burning Bunker?
(OP)
If combustion efficiency, not boiler efficiency, is the amount of heat released by the product verses the heating value then what is the best commercially available achievable combustion as a percent of Bunker or any heavy residual fuel oil and how is it best measured to prove?
I understand that a Chromatographic test is used to analyze all the gases of combustion and determine quality of combustion of the fuel product...is this correct?
What is an industry average expectation as a percent of total product combustion for any of the heavy oils...Bunker, No6 or no 7 FO? Is it possible to achieve 99% combustion and reduce emissions of unburned hydrocarbons? If not why?

Combustion is a balancing act between all the trade off's.
Proper fuel heating, good atomization and burner tip maintenance and register tuning are important keys to good fuel oil combustion, if you have the air right and in the right place.

Don't misunderstand. In my career, I have been involved in several technologies that were 'cutting edge' in their time, but all of which are accepted as the norm now. Zirconia cell based O2 trim control as one example-they said it couldn't be done when the first probe type O2 analyzers appeared on the market. Rotating vanes on coal pulverizer mills was another just to name a couple. So I am not discounting what you are presenting, just saying that I want more information.

The January 2005 issue of Power Engineering Mag. at www.power-eng.com has an interesting and informative article about catalytic combustion. You can register with them to get on their site if you aren't already.
Based on the tenor of this article, it is entirely conceivable that someone has given the customer that you saw the technology based on promises of performance.
But, the fuels involved in the process detailed in this article are Natural Gas, not resid. Are there catalysts that can deal with resid? I'm open to learn.
To answer your question, based on what I read, the lack of the need to have excess air to insure complete combustion as well as quench flame temperatures for NOx abatement would produce significant fuel efficiency improvements.

I have found that another utility is forming a committee to study/evaluate whether or not to make a demonstration test.

I don't understand your response, unless you did not read the article. I can't find any mention above in this thread of SCR. But, the article does only talk about catalytic combustion, which, of course involves the use of catalysts as does SCR, and nowhere deals with any magnetic issues.

Catalytic combustion combustion technologies are new as far as I know and yet to be made commercial. I understand they are the future for reduced NOx and effciciency improvements but are still on the board or lab.
Do you have direct link to the article? I did a search of 2005 January and got the issue topics and summaries...and only saw the SCR technology article.
Thanks

I checked with the independent power producer that is using the cells, again. The production manager stands by his numbers.
And now there is another local area utility considering these cells. They are considering doing a 'study'. These cells are not for combustion turbines, they are used on utility boilers and refinery furnaces.
