Davide Cavaliere - 'Flame in the mirror 2'
The photo is a premixed methane flame from a new type of burner that it could be used in the combustion chamber of gas turbines. This new burner was designed for reducing the CO emissions. This burner is composed from two inlets and so two different flames. The image was rotated for giving it a mirror effect. The photo show the OH emissions (a chemical specie produced during the combustion of the methane ). For taking this photo was used a ICCD camera. An Intensified CDD (ICCD) camera is an electronic camera equipped with an intensified CCD as image sensor. The sensor uses an image intensifier that is fibre optically coupled to the CCD chip to increase the sensitivity down to single photon level. This camera was coupled with a 105 mm f#4.5 Nikkor UV lens and a UVB filter 310 nm (±10 nm). This filter shows just the OH* emissions. The OH emissions are used for studying the shape flame and the stability of the flame. Acknowledgements: I would like to thank Prof. E. Mastorakos for his continuous support and Dr. F. Yuen for the contribution during the experimental work.
