最近新研制出一种已被批准为专利的重油燃烧方法,它可使低压残油(Residual fueloil)在使用通常的低压雾化空气的小型工业用油喷咀上成功的燃烧。专利发明者规定,能够使用的6~#及6~#以上的残油,系经分馏和裂化后所剩下的原油的重质部分。温度在100°F时,其粘度在100ssu(赛波特通用秒,sa ybolt seconds universal)以上,乃至900ssu。低压空气雾化型油咀的一般工作原理见图9-1。雾化空气在压力的作用下流过油管外的空气环腔,与从供油管喷出的燃料油接触并将
Recently a patented heavy oil combustion process has been developed to allow residual fuel oil to be successfully combusted on small industrial oil jets using conventional low pressure atomizing air. The inventor of the present invention stipulated that the remaining usable residues of 6 to # and 6 to # can be heavy fractions of crude oil remaining after fractionation and cracking. Its viscosity is above 100ssu (saabolt seconds universal) at temperatures up to 900ssu at 100 ° F. The general working principle of low pressure air atomizing oil nozzle is shown in Figure 9-1. The atomized air flows under pressure through the air annulus outside the oil pipe and comes in contact with the fuel oil ejected from the oil supply pipe and
