Project Objectives

Project Support- METI & NEDO

- Final Target of the EAGLE Step1 is to toward IGFC, which is combined with Fuel Cell, GT, and ST.It’s called triple combined cycle.

- Coal must be converted into an ash-free combustible gas with gasification and clean-up to produce a gaseous fuel equivalent to LNG.For the above, we set the following as a final target.1. Development of Oxygen-blown entrained-flow gasifier2. Establishment of Gas clean-up technology for fuel cells

SurveySurvey of trace elements behaviorof trace elements behavior

【Survey on trace elements behavior】• Trace elements (such as Hg, Se, As, Cl, ) from IGCC is uncertain.• Survey for the reliability of plant and environmental assessment.• Development of sampling technique for coal gas (ie. high temp. and press.).
