COAL GASIFICATION - BACK TO THE FUTURE ? PERSPECTIVE ON ATMOSPHERIC VS PRESSURIZED COAL GASIFICATION

摘要

The existing coal-based IGCC projects have not demonstrated commercial availability and reliability required for utility operation the utility industry has a "negative" perspective towards coal-based IGCC. As long as all power generating technologies continue to improve, the relative economic difference will remain the same between PC and IGCC, and IGCC will remain in the same relative economic position as it is today. Atmospheric gasification appears to be "backward" progress, but if it allows utilities to reduce IGCC's capital cost and to change their negative "perception" of IGCC, then atmospheric gasification is "forward" progress. Then, the environmental advantages of IGCC may Provide the advantage for selection of IGCC over PC.
