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.
