  • Patent number: 4348211
    Abstract: A gas generating system utilizing cellulosic waste, such as sawdust and the like, of a low BTU rating, which is partially dried on the closed top of, and then fed to the bottom of a conical generator into which a limited air supply is delivered to the upper portion of the generator where a combustion zone occurs to sinter the material and form steam and wood gas (methane) which passes to and through a heat exchange coil in an after-cooler tank in which water is heated incident to cooling the gas which successively passes through several cyclone units which successively remove dust, ash, creosote and other condensates, a blower also being included to induce a low rate of suction in the system to insure movement of the gas through the system which finally preferably is passed through a scrubber to clean the gas product of any appreciable impurities and the scrubbing water is recirculated to absorb more impurities after being stratified to remove heavy condensates and other solids.
