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.
Claims37
A system in which syngas is supplied as fuel for a burner used to direct-fire a device, the system comprising:
- a gasifier for producing syngas;
- a syngas burner for receiving syngas from the gasifier;
- and
- a booster burner disposed along a fluid path between the gasifier and the syngas burner for increasing the temperature of the syngas.
A method for using syngas as fuel in a burner used to direct-fire a device, the method comprising:
- producing syngas in a gasifier;
- increasing the temperature of the syngas using a booster burner;
- and
- providing the heated syngas to a syngas burner.
