Acording to the literature data collected by the working team, the combustion characteristics data of low-value recycled materials are not complete. Therefore, the basics of the three types of low-value recycled materials (old clothes, waste plastic bags and plastic labels for waste containers) are basic. The combustion characteristics data were collected from literature data and laboratory analysis. The results showed that the chlorine content of the plastic labels of waste containers was higher, the sulfur and nitrogen content of old clothes were higher, and the calorific values of waste plastic bags and plastic labels of waste containers were higher than that of old clothes. According to the above test data, plan the mixing ratio of low-value recycled materials to make RDF-5, and try out small batches of RDF-5 with different proportions of low-value recycled materials, and perform combustion characteristics analysis again to confirm the produced RDF-5 combustion characteristics. The best mixing ratio is used clothes 40.0%, waste container plastic label 30.0% and waste plastic bag 30.0%. Subsequent production of trial burn RDF-5 will be produced in large quantities at this mixing ratio to obtain good pellets and fuels with calorific values as close as possible to coal combustion. Mechanical equipment was production began in early October. After the granulation is completed, they are temporarily stored in OO Company. The test firing burn is 5 batches of test firing operations performed by YOO Industrial Paper Co., Ltd. OO Plant No. 2 fluidized bed boiler. The trial burn test plan matches the schedule of the sampling and testing company. The actual trial birn schedule is as follows: The trial burn time for the first to fourth batches is performed from November 1 to November 4. The trial burn operation time for the V batch is November 9 to November 11. The test trial burn operation also cooperates with the implementation of environmental monitoring operations, including air pollutant sampling and fly ash and bottom slag sampling. The sample test results are in compliance with relevant regulations. The above test data show that the mixed RDF-5 made from low-value recycled materials (old clothes, plastic bags and plastic labels for waste containers) is feasible as an auxiliary fuel for circulating fluidized bed boilers. Relevant legal procedures to provide legal basis for the implementation of low-value recovered materials as boiler auxiliary fuel.
