摘要

针对采用HT-NR3旋流燃烧器锅炉存在的水冷壁以及侧墙高温腐蚀、燃烧器喷口烧损等问题

将燃烧器扩口角度从45°改为35°

并对这2种不同扩口角度的HT-NR3燃烧器进行冷态试验研究。结果表明

与采用45°扩口的燃烧器相比

采用35°扩口燃烧器的回流区和出口气流扩展角均较小

外二次风旋流叶片的调节范围更广

对煤种的适应性更强

可有效防止燃烧器喷口结渣和烧毁

提高燃烧的稳定性

有利于降低NOx的排放。

Abstract

To solve such problems as high temperature corrosion and burner outlet burnt occurred in water wall and furnace side wall in boilers equipped with HT-NR3 swirl burners

the burner flaring angle was changed from 45°to 35°

and cold-state tests were carried out on the HT-NR3 swirl burner with the above two burner flaring angles.The results show that

compared with the burner with flaring angle of 45°

the one with that of 35°has smaller recirculation zone and outlet gas spread angle

wider regulation range of outer secondary air swirl blade and stronger adaptability for coal type.Therefore

it can prevent the burner outlet from slagging and being burnt effectively

which improved the stability of the combustion and was helpful to the reduction of NOx emission.
