Radiant syngas cooler (RSC) – quenching combination

gasification technology


Technical advantages

Higher gasification efficiency than quenching process.

By optimizing the combination of RSC and quench chamber to adjust the syngas temperature and the steam/syngas ratio.

Producing high pressure steam can meet the requirement of downstream, lower the coal consumption and pollutant emission.

Conclusion:

The demand for large scale gasifiers is now increasing in China.

Both OMB CWS gasification technology and SE Dry-feed coal gasification technology have been used, as well as the Non-catalyst POX technology.

ECUST has developed a series of gasifiers to meet the requirement of different projects. The RSC - Quenching combination gasification technology is developed.
