Method and apparatus for a feed into a gasifier utilizing a slurry

Disclosed is a feed system for a gasifier including a grinding mechanism capable of grinding a feedstock into particles of desired particle sizes. The particle sizes include solids particles larger than a first threshold size and raw fines particles smaller than a second threshold size. At least one...

Beschreibung
Zusammenfassung:	Disclosed is a feed system for a gasifier including a grinding mechanism capable of grinding a feedstock into particles of desired particle sizes. The particle sizes include solids particles larger than a first threshold size and raw fines particles smaller than a second threshold size. At least one solids separation device is capable of separating the solids particles from the fines particles and at least one solids conduit conveys the solids particles to a gasification plant while the fines particles are also conveyed to the gasification plant. Further disclosed is a method for feeding stock into a gasifier including conveying a feedstock into a grinding mechanism and grinding the feedstock into particles of desired sizes. Solids particles larger than a first threshold size are separated from fines particles smaller than a second threshold size and the solids particles and the fines particles are conveyed toward the gasification plant.
