一、前言目前国内硫磺回收装置的生产能力小至1×10~3t/a,大至1×10~4t/a。无论其生产能力如何,其生产原理都是采取克劳斯部分燃烧法,生产过程几乎类同,标定计算方法也都一样。由于燃烧炉和转化器内部都伴有化学反应,又互相关联成一个体系,计算十分繁杂。有不少地方需要试算或反算,如燃烧 I. Introduction At present, the production capacity of domestic sulfur recovery unit is as small as 1 × 10 ~ 3t / a and as large as 1 × 10 ~ 4t / a. Regardless of its production capacity, its production principle is to take part Klaus combustion method, the production process is almost the same, the calibration calculation method is the same. As the combustion furnace and converter are accompanied by internal chemical reactions, but also associated with each other into a system, the calculation is very complicated. There are quite a few places that need trial calculation or back calculation, such as burning
