Abstract
This paper addresses to the combustion characteristics in the burner using emulsified fuel newly produced with the swirl impinging mixer just before ejecting without any surfactant. According to international agreement, the restriction of exhaust emissions of the industrial burner, for instance NOx, PM etc, is getting stricter for the environmental conservation. As a countermeasure of these, the emulsified fuel, which is water and oil mixture, is one of the measures.


The emulsified fuel is made into fuel drops of uniform size, 10~20㎛, using swirl impinging mixer without surfactant. The characteristics of combustion, exhaust, and efficiency are analysed in this paper.


As a result, the emulsified fuel applied to a burner makes the flame length short and reduces excessive air. NOx and PM are also reduced up to 30% and 90% respectively. If the amount of exhaust emission is remained at the same level the fuel efficiency can be better by 4%.
