Gasification combined facility for carbon fuel including pneumatic conveying dryer

摘要

This invention relates to an integrated gasification apparatus for carbonaceous fuel, wherein high-pressure steam produced during a gasification process of carbonaceous fuel is directly used to dry the carbonaceous fuel, and steam obtained through the drying process is directly used in a water gas shift process.

主权项

1. An integrated gasification apparatus for carbonaceous fuel, comprising:
a gasifier to react carbonaceous fuel and a gasification agent to produce a syngas, wherein the gasifier includes a heat exchanger; a flash dryer to lower a water content of the carbonaceous fuel containing water fed into the flash dryer using high-pressure steam produced in the heat exchanger; and a water gas shift reactor to produce hydrogen and carbon dioxide from the steam discharged from the flash dryer and the syngas, wherein the flash dryer comprises a high-pressure feeder for feeding the carbonaceous fuel, a dryer tube for feeding the steam, a cyclone for separating the steam and the carbonaceous fuel, a filter for separating fine particles from the steam separated by the cyclone, and a storage tank for storing the carbonaceous fuel.
