采用一种新型的雾化器设计，研究了空气雾化重油喷雾火焰的结构，特别是液滴燃烧的机理。一个颗粒尺寸测量仪器和喷雾动量测量装置被用来校准这个雾化器，使参数的变化，可以由初始液滴尺寸分布，喷雾动量，燃料流量，和空气/燃料比。获得关于火焰长度、液滴燃烧状态（液滴的单独或成组燃烧）和燃烧室壁温作为初始条件的函数的信息。在此信息的支持下，推理有关的物理流动被用来提出的两个参数，其中包括初始喷雾动量，液滴尺寸分布，和燃料流量的相对值，可以给出一个很好的指示可能燃烧制度和其他重要功能的喷雾火焰。
The structures of air blast atomized heavy fuel oil spray flames, in particular, the mechanisms of droplet burning, are examined as functions of initial conditions by using a novel atomizer design. A particle sizing instrument and a spray momentum measurement device are used to calibrate this atomizer so that parametric variations can be made of the initial droplet size distribution, spray momentum, fuel flow rate, and air/fuel ratio. Information is obtained on flame length, droplet burning regime (individual or group combustion of droplets), and combustion chamber wall temperature as a function of initial conditions. Supported by this information, reasoning regarding the physics of the flows is used to propose that the relative values of two parameters, which incorporate initial spray momentum, droplet size distribution, and fuel flow rate, can give a good indication of the likely burning regime and other important features of spray flames.
