摘要

基于循环流化床(Circulation Fluidized Bed

CFB)技术的纯氨燃烧有望高效、低成本地解决氨燃烧面临的火焰传播速度低、燃烧稳定性差等问题

从而助力基于可再生能源的无碳燃料的消纳利用。构建了氨燃烧CFB整体数学模型

同时考虑了氨的均相反应及异相催化反应

探究了纯氨燃烧CFB锅炉的氨逃逸、氮氧化物等排放特性

并分析了床温、过量空气系数、空气分级、燃料分级等运行参数对排放特性的影响。结果表明:直接将常规燃煤CFB锅炉结构与运行策略应用于纯燃氨CFB锅炉会导致较高的氨逃逸与氮氧化物排放体积分数

而适当调整运行参数可以显著改善排放特性。

Abstract

Ammonia combustion with circulating fluidized bed (CFB) technology is expected to address the challenges of its low flame propagation speed and unstable combustion characteristics with high efficiency and low cost

thereby facilitating the utilization of carbon-neutral fuels derived from renewable sources. A comprehensive mathematical model for CFB-based ammonia combustion was developed

incorporating both homogeneous and heterogeneous catalytic reactions of ammonia. The emission characteristics of an ammonia-fired CFB boiler

including ammonia slip and nitrogen oxide emissions

were analyzed alongside the impact of operating parameters such as bed temperature

excess air ratio

air staging

and fuel staging. Results show that directly employing the design and operational strategies of traditional coal-fired CFB boilers for ammonia combustion of CFB boilers results in relatively high levels of ammonia slip and nitrogen oxide emissions. However

suitable adjustment of operating parameters can markedly enhance emission characteristics.
