【Haichuan’s Insights】Using Clean Fuels to Replace Part of Conventional Energy in CFB Boilers by Combusting Biomass Fuels Directly

Thread Content

On April 10, the first batch of biomass fuel purchased by Maoming Petrochemical Company arrived at the plant and was used in combination with conventional fuels, thereby replacing part of the regular energy sources with cleaner fuels. 　　It is understood that biomass fuels are primarily made from agricultural and forestry waste such as eucalyptus chips and broomwood blocks; they are compressed into shape using specialized machinery, which alters their density, strength, and combustion properties while extending their burning time. Compared to conventional energy sources, biomass fuels have a low sulfur content and are considered clean energy sources, as they can effectively reduce carbon dioxide emissions. 　　Previously, to ensure the safe blending of biomass fuel, Maoming Petrochemical conducted investigations into the practices of its affiliated units regarding the use of biomass fuel, and held technical exchanges on biomass fuel blending with the Institute of Thermal Engineering at Zhejiang University. It established quality standards and plans for the blending of biomass fuel, and implemented comprehensive inspection and monitoring during the blending process to guarantee its safe use. 　　During the co-firing period, Boiler No. 1 CFB in the Chemical Sector of Maoming Petrochemical’s Thermal Power Division operated smoothly, with emissions meeting environmental standards. Based on the results of co-firing, the proportion of biomass fuel used in co-firing will be gradually increased to 10% and 15%, which is of great significance for the company’s efforts in researching biomass fuel co-firing as well as in achieving energy savings and carbon reduction.
