摘要
氨作为一类技术成熟、储运成本低廉的零碳燃料,部分替代煤可以成为“双碳”目标下火电机组前端减碳的有效途径。针对氨作为替代燃料开展研究,利用一维火焰炉和着火炉等试验设备研究了氨与典型烟煤混合燃料的燃料特性,详细研究并分析了氨/煤混合燃料着火性能变化、不同比例氨混合燃料强化燃烧与污染物控制技术,发现氨与煤预混燃烧不利于NO_(x)控制,通过燃料分级、燃烧过量空气系数或氧量控制、空气分级燃烧,可以实现氨掺混时较低的NO_(x)生成和较好的燃烧效果,试验得出热值比例25%氨分别与典型烟煤混合燃烧时运行控制建议。
Ammonia is a kind of zero-carbon fuel with mature technology and low storage and transportation cost.Partial replacement of coal with ammonia can become an effective way to reduce carbon at the front end of coal-fired units under the dual carbon target.Ammonia fuel is studied as an alternative fuel.The fuel characteristics of ammonia and its blended fuel with typical bituminous coal are studied by using one-dimensional flame furnace and ignition furnace.The ignition performance changes of ammonia/coal blended fuel,the enhanced combustion and pollutant control technology of different proportions of ammonia blended fuel are studied and analyzed in detail.It is found that the pre-blended combustion of ammonia/coal is not conducive to NOx control.Through fuel grading,combustion excess air coefficient or oxygen control,and air staged combustion,lower NO_(x) generation concentration and better combustion effect can be achieved during ammonia blending.The operation control suggestions of 25%ammonia mixed with typical bituminous coal are obtained.
