Mono-nitrogen oxides (NOx) including NO and NO2 are byproducts of combustion where it occurs in the presence of nitrogen. Since the composition of the atmosphere is 78% nitrogen, this would include most places where this combustion occurs. These NOx gases: …react to form smog and acid rain as well as being central to the formation […]

Back in January, I shared some thoughts from Emerson’s Doug Simmers on improving combustion in a post, Optimum Combustion for Reduced Greenhouse Emissions. He’ll be presenting later this year on flue gas analysis and I was able to get my hands on a rough draft. I’ll highlight a few of his early ideas and hope […]

If you’re in the coal-fired power generation business, you may know that Coal-Gen 2009 is going on this week. During the conference, a Midwest power producer and the Emerson Power & Water Solutions team gave a joint presentation on combustion optimization. Emerson’s Jeff Williams, one of the presenters, was kind enough to send me a […]
