Research Progress on Multi-Waste Treatment Technology Based on Circulating Fluidized Bed Combustion
With the continuous growth of China's economy and the improvement of residents'quality of life,the industrial production process inevitably generates a large amount of solid waste,waste gas,and wastewater.Effective management and resource utilization of these wastes have become urgent issues to address.Circulating fluidized bed(CFB)combustion technology,with its high efficiency and environmentally friendly advantages,has wide application in the field of waste treatment.As an advanced clean combustion technology,CFB demonstrates excellent fuel adaptability,low pollutant control costs,and flexible load adjustment capabilities,significantly promoting the comprehensive utilization of wastes.This paper introduces the diversified applications of CFB combustion technology in the treatment of solid waste,waste gas,and waste liquid,covering key points in the following areas:(1)Solid waste treatment.In waste incineration,key parameters such as air balance,combustion temperature,and secondary air need to be closely monitored.For the treatment of coal processing by-products,focus should be on bed temperature control,desulfurization,and denitrification processes.In sludge treatment,optimizing combustion temperature,controlling fly ash carbon content,and reducing NOx emissions are essential.The combustion of agricultural and forestry waste requires attention to ash content,alkali metal content,fuel form,and moisture content to address potential issues such as fouling,ash deposit,corrosion,or in-furnace slagging.(2)Waste gas.For sintering flue gas and chemical tail gas,it is important to optimize combustion temperature and desulfurization and denitrification strategies.Additionally,analyzing and regulating the combustion conditions and components of chemical tail gas are crucial.(3)Waste liquid.CFB combustion technology offers viable treatment paths for organic waste liquid and saline wastewater.Special attention must be paid to combustion temperature,the type and amount of additives,and flue gas purification measures.In conclusion,CFB combustion technology shows great potential in the field of waste treatment,and it not only effectively reduces environmental pollution but also promotes the recycling of resources.
