English: A schematic showing the wood gasifier built by Dick Strawbridge and Jem Stansfield for the show "Planet Mechanics".

Parts:

• A: wood
• B: fire
• C: air inlet (air going to 4 nozzles)
• D: reduction zone; contains charcoal; smoke goes trough the accumulated charcoal and reacts with it. H2O and CO2 becomes H2 and CO
• D1: top grating (movable)
• D2: lower grating (not movable)
• D3: handle: used to stir up the wood to provide evenly high temperature over top grating
• E: smoke
• F: single-cyclone seperator (coarse filter)
• G: partially filtered smoke
• H: radiator (reduces heat of gas and hence condenses the gas, making it more flammable/potent)
• I: cooled, partially filtered smoke
• J: fine filter (consisting of clay balls on top of a grating)
• K: wood gas (= fully filtered, cooled smoke)
• L: air/gas mixer (replaces IC engine carburetor)
• L1: air inlet valve (operated via handle mounted to gear stick)
• L2: choke valve
