引言最近,专烧重油的锅炉的容量日趋增大,随之而来重油喷燃器的容量也在增大。重油燃烧可有几种燃烧方法,但就大容量而言,较易实行且又经济的方法是目前最广泛采用的喷雾燃烧。此种方法是以增加油滴的细粒化程度来增强其燃烧性。喷雾燃烧的雾化方法是把燃料高度加压,并以此压力通过喷咀来实现油滴雾化;此外也有利用蒸汽或压缩空气来实现雾化。
INTRODUCTION Recently, the capacity of boilers dedicated to burning heavy oil has been increasing, with the consequent increase in the capacity of heavy oil burners. There are several combustion methods available for heavy oil combustion, but for large capacity, the most practicable and economical method is by far the most widely used spray combustion. This method is to increase the degree of granulation of oil droplets to enhance its combustibility. Spray combustion atomization method is to fuel the high degree of pressure, and the pressure through the nozzle to achieve oil droplets atomization; also use steam or compressed air to achieve atomization.
