In order to meet the development trend of incinerator technology with high efficiency and suitability to Vietnam's conditions in the future, the research focuses on developing technical instructions for the operation process of fluidized bed incinerator technology (BFB, CFB) in domestic solid waste treatment. The content of the article presents the procedures for starting the incinerator, the operation of the incinerator and the process of stopping the incinerator. The research results are aimed at providing materials for use in training engineers specializing in urban environmental engineering. It is also a reference for engineers who directly perform operational management at waste power plants or scientists and managers interested in research in the field of domestic solid waste management.
