  • Method for generating syngas from biomass including transfer of heat from thermal cracking to upstream syngas
    Patent number: 8936886
    Abstract: Biomass is gasified to generate syngas. The syngas is subjected to thermal cracking. Heat from syngas exiting a thermal cracking stage is transferred to syngas entering the thermal cracking stage. Biomass gasification apparatus may include a thermal pathway connected to transfer heat from an outlet of a thermal cracking process to an inlet of the thermal cracking process. Energy efficiency is enhanced. Syngas may be used as fuel for engines or fuel cells, burned to yield heat, or processed into a fuel.
    Type: Grant

  • Control of syngas temperature using a booster burner
    Patent number: 8882493
    Abstract: A method and system for fueling of a burner in a direct-fired device using syngas. A gasifier produces syngas from a carbonaceous feedstock such as biomass. The syngas is fed to a syngas burner. A booster burner disposed between the gasifier and the syngas burner increases the temperature of the syngas. The booster burner may be provided with an approximately stoichiometric or sub-stoichiometric amount of oxidant. Operation of the booster burner may be regulated based on the temperature of the syngas. The syngas burner may be used to direct-fire a device requiring a relatively high flame temperature, such as, for example, a lime kiln.
