一、前言关于燃烧系统的控制,多余的空气量对燃烧效率和大气环境都是很重要的,特别是裂解炉的燃料消耗量占整个乙烯装置的80～90%,所以整定适当的空燃比对节能、减少NO_x 生成量都是有益的。大阪石油公司在1981年对裂解炉的仪表进行更换,实现了东芝 TODIS-200系列的 I. INTRODUCTION With regard to control of the combustion system, the excess air volume is important for both combustion efficiency and atmospheric conditions. In particular, the fuel consumed by the cracker accounts for 80-90% of the total ethylene plant, so setting the appropriate air-fuel ratio Energy saving, reducing NO_x production are beneficial. Osaka Oil Company in 1981 cracker instrumentation to replace the Toshiba TODIS-200 series
