摘要

对某300 MW四角切圆锅炉60%负荷工况掺烧20%氨气进行模拟研究，分析煤粉锅炉掺氨燃烧过程，寻求最佳的煤氨共燃方案以保证最优燃烧效率以及最低的污染物排放。采用数值模拟方法，通过调整氨气燃烧器的位置和燃尽风比例，系统分析了炉内烟气温度场、燃烧组分摩尔分数分布、燃烧特性以及炉膛出口NO

排放水平。综合分析表明，在燃尽风比例为33.5%时，将氨气燃烧器布置在顶层三次风与CD层二次风的位置为最佳煤氨共燃方案。该方案在保证燃烧效率与稳定性的同时，可将NO

排放水平控制在与纯燃煤工况相当的NO

排放水平，这为大型燃煤电厂实现清洁高效燃烧提供了新的思路。

Abstract

A simulation study on a 300 MW tangentially-fired boiler with 20% ammonia doping at 60% load was carried out to analyze the combustion process of ammonia doping in pulverized coal boiler

and to seek for the best coal-ammonia co-combustion scheme to ensure the optimal combustion efficiency and the lowest pollutant emission. By adjusting the position of ammonia burners and the ratio of the separated over fire air

the temperature field of the flue gas in the furnace

the molar fraction distribution of the combustion components

as well as the combustion characteristics and the NO

emission level at the furnace outlet were systematically analyzed using

numerical simulation. The comprehensive analysis shows that

the best coal-ammonia co-combustion solution is to place the ammonia burner on top layer(tertiary air) and the CD layer(secondary air) when the ratio of the separated over fire air is 33.5%. This scheme ensures the combustion efficiency and stability while controlling the NO

emission level comparable to that of the pure coal-fired condition

which provides a new way of thinking for largescale coal-fired power plants to realize clean and efficient combustion.
