ENTRAINED FLOW GASIFIER WITH INTEGRATED RADIATION COOLER

摘要

The invention relates to an entrained flow gasifier designed as a component for an Integrated Gasification Combined Cycle (IGCC) plant of optimized efficiency, where the raw gas initially flows through a waste heat unit designed as a radiation cooler and subsequently flows through a full water quench. The result is a higher ratio of steam in the raw gas, which decreases the medium-pressure steam supply before the water-gas shift and thus improves efficiency in IGCC plants with CO2 separation.
