New Coal Policy toward 2030

Japanese government proposed New coal policy toward 2030to promote Clean Coal Technology in 2004 .

Activity of Electric Power Company

-- Promote high-efficiency use-- Reduce/utilize environmentally harmful byproducts-- Cultivate new possibilities of coal utilization -- Expand supply potential of coal-- Improve efficient procurement of coal

Five Basic Directions

-- Develop high-efficiency power generation systems, such as USC, IGCC and IGFC

-- Promote utilization of biomass by co-fireing in pulverized coal power plant

Specifications of 3T/D New Coal Gasifier

CRIEPI has been carrying out a series of R&D including the experiments using 2.4 T/D coal gasifier 1983-1995 in order to support the design and operation of IGCC Pilot Plant (200 T/D).

CRIEPI constructed the new gasifier to develop advanced IGCC technologies required to commercialize IGCC.


CRIEPI’s Numerical Simulation Technology for Coal

Gasifier to support IGCC demonstration project

�Numerical simulation makes it possible to predict the physical values which are hard-to-measured.

�Numerical simulation results show good agreement with experimental results.
