Research output: Contribution to journalArticlepeer-review


A new concept of gasification power generation systems fueled by coal, RDF and various kinds of wastes using high temperature air is proposed. Cycle analyses of these IGCC and boiler systems are done. The calculation shows that heating value of syngas almost doubles when we increase the gasification air temperature from 25°C to 1 000°C. More than 45% thermal efficiency is obtainable both for coal and RDF by employing the new high temperature air blown IGCC system. This IGCC system is applicable to various wastes including low grade wastes such as sludge.
