| 摘要 |
A method for the gasification of solid fuel to produce combustible effluent, comprising the steps of: partially oxidizing a biomass fuel in a first oxidation zone to produce char; reducing the char in a reduction zone to form ash; further oxidizing any char residue ash in a second oxidation zone; and extracting the combustible effluent produced in the above steps, by a discharge pipe wherein in the first oxidation zone the gas flow is in the same direction as fuel flow and in the second oxidation zone the gas flow is in the opposite direction to the fuel flow.
