A development plan of “Advanced supercritical coalfiring power plant technology with operation temperature of 700℃”(AD700) started from 1998 in Europe has been presented

including feasibility study

preparation works

parts demonstration

as well as advancement in aspect of material research at present. Study shows that the related technologies to be economical and feasible

but research work in aspects of design and manufacture should be simutaneously developed

to reduce the materials consumption and to lower the construction cost. It is planning to construct a demonstration power plant at present.
