Research progress on zero-carbon fuel blending combustion technology of coal-fired circulating fluidized bed
摘要
Abstract
Co-firing zero-carbon fuels in coal-fired power plants is one of the important paths to realize low-carbon emissions in power industry,and the common zero-carbon fuels blended at present are biomass,ammonia,and hydrogen,etc.The researches on co-firing zero-carbon fuels in coal-fired circulating fluidized bed(CFB)boilers are discussed,the technical principles and advantages of the technology are analyzed,and the future technical challenges and development trends of the technology are discussed,by combining the characteristics of biomass,ammonia and hydrogen fuels with the progress of the research on blending,to provide theoretical and technical support for the realization of low-carbon emissions from coal-fired boilers.Based on the fluidized combustion characteristics of CFB boilers,the basic fuel characteristics,combustion characteristics and pollutants emission characteristics of the three zero-carbon fuels after blending,problems and future development directions are analyzed.Although there are certain limitations and technical challenges in the co-firing of all three zero-carbon fuels,the optimization of the combustion process and the control of pollutant emissions can be realized through the organization of the gas-solid flow field,the deep grading of fuel or air,and the coupling of other technologies.Co-firing zero-carbon fuels in coal-fired CFB boilers is a feasible route for carbon emission reduction,which helps to develop a new generation of flexible low-carbon coal-fired power generation technologies in CFB boilers,and provides technical support for the promotion of low-carbon transformation of the energy structure in achieving"dual-carbon"target.关键词
