Describe the atomization process of liquid fuel
Atomization should be regarded as a prerequisite for the combustion of liquid fuels. Only when atomization is very fine can the unit surface area of oil particles be large enough to accelerate evaporation. But only rapid evaporation is not enough, and the gaseous products that evaporate must be quickly mixed with air in order to burn quickly. On the contrary, the faster the combustion, the heat generated will heat the fresh oil mist faster, causing it to evaporate. Macroscopically speaking, the atomization of oil and the mixing of oil and air depend on fluid dynamics conditions, and the high temperature in the combustion chamber mainly depends on the heat balance conditions in the combustion chamber. These can be controlled by changing operations and structural parameters. However, the evaporation of oil Pyrolysis and cracking occur spontaneously in the combustion chamber When conditions such as fuel type, atomization particle size, atmosphere, and temperature are constant, the speed and products of these processes are determined. At the same time, conditions such as atomization particle size, atmosphere, and temperature are determined by atomization and mixing conditions. In short, the main means of controlling oil combustion is to control the atomization and mixing processes. In the face of oil evaporation, pyrolysis, cracking, and other processes, they are influenced by the actual and mixing processes Sound without direct control.Author：Ebico
