Abstract

A movable grate (50) is mounted on an upright pipe (36) is disposed within and spaced above the bottom of an upright vessel (12, 14) of a gasifier. A layer (54) of loose, high heat resistant, ball-like elements is established on the grate (50). Biomass is continuously charged into the vessel (12, 14) above the grate (50) and combusted so as to form a char-bed of biomass immediately above the layer (54). Combustion-­ supporting gas is introduced into the char-bed and drawn downwardly through the char-bed, the layer (54) and the grate (50). The gas generated thereby is withdrawn from the vessel (12, 14) below the grate (50) by means of a fan (72). The grate (50) is moved so as to move the individual elements of the layer (54) and effect gravitational filtering of char-coal particles from the char-bed. The char-bed is agitated and combustion-supporting gas is introduced into the char-bed by the pipe (36) and the tubular branches (62, 64, 66).
