燃烧技术关键之一是必须有良好的燃烧器,而液态燃料燃烧器的优劣取决于雾化效果及其流场分布特性.由于液滴表面积与滴径成反比,例如1cm~3的燃油雾化成平均直径为1m/m时,表面积为60cm~2,当雾化成平均滴径为50μ时,则表面积约增至1200cm~2,表面积增大的结果是使燃烧速度迅速提高并使燃烧效率递增.但是鉴于雾化过程非常复杂,即使单相液滴的雾化尚未建立起系统的理论,只有半经验阐述.
One of the keys of combustion technology is to have a good burner, and the advantages and disadvantages of the liquid fuel burner depends on the atomization effect and the distribution of the flow field.Because the droplet surface area is inversely proportional to the droplet diameter, for example, 1cm ~ 3 fuel mist When the average diameter is 1m / m, the surface area is 60cm-2. When atomized into an average droplet diameter of 50μ, the surface area increases to about 1200cm-2. As the surface area increases, the combustion speed increases rapidly and the combustion efficiency increases However, since the atomization process is very complicated, even though the atomization of single-phase droplets has not established systematic theory, only semi-empirical explanation is given.
