The utility model discloses a ground torch furnace body with high-intensity ceramic fiber modules. The ground torch furnace body with the high-intensity ceramic fiber modules comprises a furnace body. A plurality of high-intensity ceramic fiber modules are installed on the inner wall of the furnace body through anchoring parts. A ceramic fiber interlayer blanket is arranged between two adjacent high-intensity ceramic fiber modules including an upper high-intensity ceramic fiber module and a lower high-intensity ceramic fiber module. The intensity of each high-intensity ceramic fiber module is larger than the intensity of the ceramic fiber interlayer blanket. The anchoring parts are arranged inside the high-intensity ceramic fiber modules. One end of each anchoring part is connected with the inner wall of the furnace body in a welded mode. The other end of each anchoring part is fixedly connected with a nut of each anchoring part. The ground torch furnace body with the high-intensity ceramic fiber module has the advantages of being simple in structure, reasonable in design, convenient to install and use, good in use effect, and incapable of burning the high-intensity ceramic fiber modules which are heat-insulating when in a large number of burning in air, prolonging service life, and preventing safety accidents.
