In February 2003, Hitachi was asked by
MidAmerican Energy Company in Iowa U.S.,
through Mitsui & Co. Energy Development, Inc.,
to execute the EPC of the Council Bluffs Energy
Center, Unit 4, an 870-MW (gross) capacity
power plant. This is the first large-capacity coal-
fired EPC project for Hitachi in the U.S. This
paper describes the technical features of the
Council Bluffs Energy Center, Unit 4 project. This
plant adopts PRB (powder river basin) coal-fired
super critical once-through, sliding pressure,
BHK (Babcock-Hitachi K.K.)-type Benson
boiler under steam condition of 25.3 MPa•g,
566/593
*C, a four-flow tandem compound
turbine, with long 40-inch last stage blades, the
largest-class two-pole generator, and cooling
towers for circulating water. In addition, we
adapted a De-NOx unit, a DFGD (dry flue gas
desulfurization) unit, and highly efficient fabric-
filter dust bags to satisfy the environmental
regulations.
