ON THE NATURE OF THE FLAME EMISSION SPECTRUM OF CRUDE OIL BLAZE AT BAGHJAN

A large of flame occurred at Baghjan (27.583090 N,95.40180 E) as a result of oil well blow out. The present work reports the spectra of the blaze which have been recorded with the help of a Mini USB Spectrometer with spectral range of 200 – 1200 nm. Assignments of the prominent emission and absorption peaks have been made. Apart from the absorption bands of water vapour and atmospheric oxygen the presence of sodium emission line has been identified. On the basis of the assumption that Baghjan flame qualifies as a black body the surface temperature of the flame has been estimated to be approximately 41400 K. Whispering gallery made in atmosphere has been proposed to explain the roaring sound that can be heard from a distance of 15 Km from the blaze.
