The second worm 202 is mounted to the output 204 of the turboexpander 201 and meshes with the second worm wheel 203. The second worm wheel 203 is mounted to the lower end of the first worm 198. A second steam guide 199 is installed at the top of the carbonization tank 11, and the second steam guide 199 is communicated with the inlet 205 of the turboexpander 201. The turbo expander 201 has an inlet 205 and an outlet 206, and after the high temperature steam enters the turbo expander 201 from the inlet 205, the output 204 of the turbo expander 201 drives the second worm 202 to rotate, the second worm 202 drives the second worm wheel 203, and the second worm wheel 203 drives the first worm 198 to rotate, so as to facilitate the rotation of the blower blade 196.

The outlet 206 of the turboexpander 201 is in communication with the steam generating tank 12 to direct the reduced temperature steam back into the steam generating tank 12 for reheating the reduced temperature steam and passing it into the carbonisation tank 11 for utilisation.
