Research Progress on Utilization of Arundo Donax L. Combustion

ObjectivesArundo donax L., as a high-yield energy crop suitable for intensive cultivation, shows great potential for large-scale replacement of coal in power generation and CO2 emission reduction. Under China’s “dual-carbon” goals and the requirements of low-carbon transformation for coal-fired power units, vigorously developing clean and efficient combustion technologies using Arundo donax L. as an energy crop offers an important low-carbon energy pathway well-suited to China’s national conditions. Understanding the current research status of Arundo donax L. combustion is crucial for guiding the utilization of its combustion in China. To this end, the research progress on the combustion and utilization of Arundo arundo is reviewed, aiming to provide reference for the large-scale utilization of biomass energy.MethodsThe study conducts a comprehensive investigation into the utilization of Arundo donax L. combustion through literature research methodology, systematically summarizing and analyzing existing research findings. It summarizes the fuel characteristics of Arundo donax L., pre-treatment methods and performance, the characteristics of combustion and pollutant emissions, and industrial-scale tests of Arundo donax L. combustion. Additionally, the study discusses the environmental effects of its cultivation.ConclusionsArundo donax L. shows significant potential for large-scale replacement of coal in heating and power generation. Given the requirements of low-carbon transformation for coal-fired power units in China, co-firing Arundo donax L. in power plants shows great potential.
