Embodiment 1
[0024] Example 1 Select a coal sample with a high ash melting point from a power plant in Shanxi, prepare a coal powder sample according to the above-mentioned standard method, use an intelligent ash fusion tester to analyze and obtain a coal ash deformation temperature of 1420 ° C, and use a 6% ratio of papermaking sludge flux powder Add it to the high ash melting point coal powder sample of the power plant, and mix evenly to prepare a mixed ash sample.
Embodiment 2
[0025] Example 2 Select a coal sample with a high ash melting point from a certain power plant in Sichuan, prepare a coal powder sample according to the above-mentioned standard method, and analyze it with an intelligent ash fusion tester to obtain a coal ash deformation temperature > 1450°C. The ratio is added to the high ash melting point coal powder sample of the power plant, and the mixed ash sample is prepared after mixing evenly.
Embodiment 3
[0026] Example 3 Select a coal sample with a high ash melting point from a company in Xinjiang, prepare a coal powder sample according to the above-mentioned standard method, use an intelligent ash fusion tester to analyze and obtain a coal ash deformation temperature of 1248 ° C, and use a 10% ratio of papermaking sludge flux powder Add it to the company's high ash melting point coal powder sample, and mix it evenly to prepare a mixed ash sample.
