Bioliquid refers to various types of liquid biomass fuel commonly acquired from residues of agricultural/food industry and biodiesel production. With the benefits of renewable energy and reduced pollutants emission, bioliquid can fully or partially displace fuel oil burned in a boiler for heat and/or electricity. This study analyzed the detailed combustion and heat transfer characteristics of bioliquid fully displacing heavy fuel oil in a 100 MWe capacity boiler. The computational fluid dynamic (CFD) modeling was established for the bioliquid combustion and heat transfer in tube bundles of superheaters/reheaters. The results were compared with the actural demonstration data in the plant, which was in a satisfactory agreement in terms of temperature and heat flux. The CFD model can, therefore, play an important role in assessing different types of bioliquid and optimizing the operation conditions.
