一、前言 气体燃料的广泛应用是因其诸多特殊优点的显示而越来越被人们所亲睐。在国外,由于受燃料政策的限制,无论是工业上还是民用上,大多使用高品位(即高热值)的燃料,而对一些热值在1000kcal/kg以下的低品位燃料却很少使用,尤其是日本及西方等一些工业发达国家,在这方面发展较迅速。我国在冶金、石油、化工等行业中应用气体作为燃料也在日益发展。由于我国在该行业中起步较晚,对燃气烧咀的研究还不透彻,特别是有不少单位的燃 I. INTRODUCTION The widespread use of gaseous fuels is more and more favored by people because of the display of many special advantages. Abroad, due to fuel policy restrictions, whether industrial or commercial, most of the use of high grade (ie, high calorific value) fuel, and some calorific value of less than 1000kcal / kg fuel is rarely used, especially Japan, the West and some other industrialized countries have developed rapidly in this respect. China’s metallurgy, petroleum, chemical and other industries in the use of gas as fuel is also growing. As China started late in the industry, the study of gas burning Tsui is still not thorough, in particular, there are many units of the burning
