The application belongs to the technical field of surface modification and relates to a system and method for preventing the inner wall of a fly ash low-temperature pyrolysis furnace from being caked, which comprises the following steps: S1, inner wall surface pretreatment: performing sand blasting polishing treatment on the inner wall of the low-temperature pyrolysis furnace to remove surface rust, residual caked substances and caking force points, then cleaning surface oil stains with an organic solvent, and then blowing dry with high-pressure air and removing residual dust; S2, hydrophobic coating spraying and curing: uniformly spraying a hydrophobic coating material on the inner wall surface treated in step S1, controlling the coating thickness to be less than 100 microns, and then putting into use after natural curing and static curing; and S3, intermittent high-pressure inert gas blowing during operation: in the operation process of the low-temperature pyrolysis furnace, the high-pressure gas blowing subsystem sprays high-pressure inert gas to the inner wall of the low-temperature pyrolysis furnace in an intermittent and instantaneous burst mode to remove the fly ash initially adhered to the inner wall and inhibit the formation and growth of caking points.
