<p>An apparatus for producing combustible gases from biomass feeds comprising an outer cylindrical structure (101) being defined by a sidewall (102), a bottom supporting base (103) and a substantially tapered top (104); an inner cylindrical structure (105) being enclosed concentrically within the outer cylindrical structure and having a first opening at its top, a sidewall (106) and a base seated on the bottom supporting base (103) such that a gap between the sidewalls (102, 106) of the outer (101) and inner cylindrical structure (105) which forms an air passage connecting to an air chamber is defined within the inner cylindrical structure (105) through the first opening; wherein the air chamber is tapered towards a second opening (109) at the bottom of the inner cylindrical structure (105); a feed inlet (107) being installed adjacent to the bottom of the outer cylindrical structure (101) and connecting to the air passage; an air inlet pipe (121) being connected to the feed inlet (107); an outlet pipe (108) extending from the tapered top (104) and connecting to the upper portion of the air chamber within the inner cylindrical structure (105); and a waste collection assembly consisting of a rotary valve (114) and a waste chamber (115) connected to the second opening (109); wherein the air passage allows a cyclonic vortex of a mixture of air and the biomass feeds to swirl upwards inside the outer cylindrical structure (101) and downwards into the inner cylindrical structure (105) upon reaching the tapered top (104) of the outer cylindrical structure (101) to discharge ash through the second opening (109) into the waste chamber (115), resulting in the vortex to swirl upwards from the tapered bottom of the inner cylindrical structure (105), driving the produced combustible gases out of the inner cylindrical structure (105) through the outlet pipe (108).</p> |
