ポット式燃焼器のすす排出パターンとすす低減化

抄録

A pot-type burner has been widely used for home heating appliances because of having several advantage such as wide turn-down ratio, low noise combustion, simple construction and so on. However, the most disadvantageous point is that the pot-type burner generally has a luminous, smoky flame. Therefore, soot emission and soot reduction of the pot-type burner has been studied semi-analytically and experimentally. (1) Soot emission of the pot-type burner can be explained by the simple calculation model which is determined by combining soot formation rate in the flame with soot recombustion rate in the combustion chamber. (2) Increase of primary air ratio in the premixed region leads to better soot emission. (3) Soot reduction of the pot-type burner can be obtained by combining the combustion process of conventional pot-type burner with that of vaporizing burner.
