SOLUTION: A louver 10 is installed around ceramic filters 7, and heat resistant solid particles 8 having a size slightly larger than the pore diameter of the filter 7 are packed between the filters 7 and the louver 10 to form a solid particle layer 9. Dust in gas 5 to be treated is removed by the surface of the particle layer 9, and residual dust is introduced to the inside of the particle layer 9 to be collected on the surface of the filters 7. The dust is removed by a method in which backwash gas 6 is introduced from the dust, and the particle layer 9 around the filters 7 is moved downward while the gas being supplied from the inside of the filters 7, discharged with the dust from a solid particle outlet line 20 outside the system, and supplied from above.

SOLUTION: This gasifying apparatus has plural stages of burners 90, 6 and 7 having an attaching-suppressing burner (B) 90 generating much amount of unburnt char at the top stage in a gasifying part converting a combustible component of a fine powder solid raw material (R) to a generated gas (G) containing abundant carbon monoxide and hydrogen by keeping R at a temperature higher than the melting point of ashes of R and the ash component to slag (S). Supplying lines 8 and 9 of R and an oxidant are connected to the burners 90, 6 and 7, and a heat-recovering part recovering heat of G is provided over the gasifying part through a contracting flow part 12 of G and a slag-cooling part granulating S is provided below the gasifying part. The burner B 90 is, e.g. provided with a jetting direction of a jetting port of R opposed to the contracting flow part 12 and a diameter of a revolving virtual circle of jetting R is set to be less than the diameter of the contracting flow part 12.
