Beschreibung
Zusammenfassung:	This invention involves with a gasification system, which includes a gasifier, which gasifier comprises a gasification chamber for producing syngas from coal slurry and a quench chamber for cooling the syngas from the gasification chamber. The mentioned gasification system also comprises preheater located in the quench chamber for utilizing heat in the quench chamber to preheat the coal slurry before the coal slurry enters the gasification chamber. Wherein, the preheater comprises a pipe device defining a passage for the coal slurry to pass through, the passage in communication with the gasification chamber and upstream of the gasification chamber in a flow direction of the coal slurry. This invention also involves with a preheater used in the mentioned gasification system and the gasification method of the mentioned gasification device.
