Abstract
A downdraft-updraft gasifier () and method for the gasification of biomass and waste to produce combustible effluent, the gasifier comprising: a fuel valve () for loading solid fuel () into a first oxidation zone (); a first throat () defining the lower edge of the first oxidation zone (); a second throat () defining the lower edge of a second oxidation zone (); a reduction zone () linking the first oxidation zone () to the second oxidation zone () and a vortex discharge pipe () for the combustible effluent. The method includes steps of: partially oxidising a biomass fuel in the first oxidation zone () to produce char; reducing the char in the reduction zone () to form ash; further oxidising any char residue in the ash in the second oxidation zone (); and extracting the combustible effluent produced in the above steps, by the discharge pipe ().
