Fractal dimension and its relation with fixed carbon and volatile have been studied. Bring up a new concept of economic granule of coal powder in coal fired thermal power plant.

Coal granule activated carbon high quality anthracite as raw materials, adopting advanced technology refined but become, the appearance of a black amorphous particles.

This paper discussed one new way to treat exhaust gas in test equipment. Firstly wipe off the solid granule of exhaust gas by gravity sedimentation chamber, then absorb the gas of HF by active carbon.
