Abstract: Zhundong coal, characterized by its abundant reserves and superior quality, serves as a crucial thermal coal of significant strategic value to our country. The high alkali metal content in Zhundong coal renders it susceptible to ash deposition, fouling, and slagging during combustion, thereby leading to effects on boiler safety and economic operation. The circulating fluidized bed boiler's low combustion temperature and high adaptability to various coal types give it a natural advantage in burning Zhundong coal, and it has become a pivotal technology for the clean and efficient utilization of Zhundong coal. Incorporating literature and practical engineering investigations, analyzes and summarizes the typical characteristics of Zhundong coal and fouling and slagging characteristics, co-firing material applications, and full burn application in circulating fluidized bed boiler. In general, the circulating fluidized bed boiler demonstrates excellent adaptability to Zhundong coal’s low ash content, medium to high/high moisture content, medium to high volatile matter content, medium to high heating value, and the characteristics of coal ash with high alkali metal and alkaline earth metal content. Operational circulating fluidized bed boiler can achieve a blending ratio of up to 85% with Zhundong coal. Waste materials such as coal gangue, gasification slag, and bottom ash, which cannot be utilized by pulverized coal boiler, can serve as cost-effective cofiring material in circulating fluidized bed boiler. Through optimization design and other measures, circulating fluidized bed boilers can achieve more than 90% blending ratios or even pure combustion of Zhundong coal.
