Abstract
The authors conducted NO emission test by burning several kinds of oil fuel in a test furnace and compared on the basis of their kinds and components, the NO emission characteristics thereby obtained.
For the purpose of extracting oil-fuel components, the authors broke down oil fuels by solvent extraction with
n-hexane and benzen, in accordance with the One's rapid method. The test results indicate that the NO production greatly various with oil-fuel components, which can be indicated as follows.
Light oil≤Top from vacuum distillate<Maltene from residual oil<Maltene from vacuum residual oil<Asphaltene from vacuum residual oil>β-resin
The authors therefore concluded that the heavier the oil fuel burned, the greater the amount of NO produced, and that the amount of NO emission could be predicted based on the solvent extraction data.
