Thread Content
China National Petroleum Corporation has been granted an invention patent: “A coal-fired circulating fluidized bed boiler system incorporating biomass and sludge in its fuel mixture.” According to data from the Tianyancha app, China National Petroleum Corporation (601857) has obtained a new invention patent, titled “A coal-fired circulating fluidized bed boiler system incorporating biomass and sludge in its fuel mixture.” The patent application number is CN202310988405.X, and the date of grant is October 21, 2025. Patent Abstract: The present invention relates to the technical field of coal-fired circulating fluidized bed boilers, and in particular to a coal-fired circulating fluidized bed boiler system that incorporates biomass and sludge in its fuel mixture ； It includes a biomass pretreatment system, a sludge pretreatment system, a biomass syngas generation system, and a circulating fluidized bed boiler; the biomass pretreatment system, the sludge pretreatment system, and the biomass syngas generation system are each connected to the interior of the circulating fluidized bed boiler ； The biomass pretreatment system is used to divide biomass into coarse biomass material and fine biomass material ； The sludge pretreatment system is used to separate the sludge into dry sludge and wet sludge ； The biomass syngas generation system uses fine biomass as input, and is used to react this fine biomass with a gasifying agent to produce syngas ； It helps to improve the combustion effect, reduce costs, and ensure complete combustion inside the furnace.
