Research progress on NOx formation characteristics of coal-fired power plant boilers with ammonia injection
摘要
Abstract
The experimental data and simulation studies on ammonia co-combustion in coal-fired power plants in recent years are investigated,with a focus on the effect of ammonia fuel on NOx generation.Through experimental observation,numerical simulation,and theoretical analysis,the spatial distribution of soot and polycyclic aromatic hydrocarbons(PAHs)during combustion is directly observed using high-speed cameras,laser-induced ignition(LII)method,and laser-induced fluorescence(PAH-LIF)method.It finds out that,the generation of NOx during ammonia combustion is significantly higher than that of the conventional hydrocarbon fuels.Reasonable design of ammonia nozzles and selection of appropriate injection positions can significantly reduce the NOx generation.The ammonia blending combustion technology provides a promising approach for achieving low-carbon transformation of coal-fired power plants.Although there are still challenges in the industrial application of large-scale ammonia blending combustion technology,the application prospects of ammonia fuel in coal-fired power plants are broad through continuous experimentation and technological optimization.Future research should continue to focus on the generation and emission of other pollutants during the process of ammonia combustion,and explore in depth the transformation behavior of minerals in coal in the combustion environment,providing theoretical and practical support for the industrialization of ammonia combustion technology.关键词
