Embodiment 1
[0038] Taking the Hongliu coal (HL coal) used in liquid coal-water slurry gasification for liquid slagging in Ningxia as the raw coal, determine the method that can be used to reduce the coal ash melting temperature of the raw coal, including the step of adding flux to the raw coal , where the determination method of flux is as follows:
[0039] (1) Obtain effective samples from HL coal, and grind and ash part of the coal samples to obtain HL standard coal ash samples;
[0040] In addition, in order to verify whether adding the method of the present invention can reduce the melting temperature of HL coal, the inventor also measured the ash melting temperature of the HL standard coal ash sample, that is, the coal ash deformation temperature, softening temperature, and hemispherical temperature of the standard coal ash sample were respectively obtained. temperature and flow temperature. The specific data are shown in Table 1:
