OVERVIEW |
In recent years, from the viewpoint of environmental conservation, it has become a top priority to improve the heat efficiency of thermal power plants.
Under such circumstances, in December 2003, a 1,000-MW coal-fired power plant with the world's highest efficiency — Unit No. 1 of Hitachinaka Thermal Power Station of The Tokyo Electric Power Co., Inc. — was put into service.
This generator consists of a coal-fired boiler with an extremely high critical pressure and a main steam temperature of 600°C as well as a state-of-the-art steam turbine with 41-inch-long (about 104 cm) final-stage turbine blades.
Hitachi, Ltd. was in charge of the design and construction of the facilities for these two main components (i.e. the boiler and turbine) of Unit No. 1.
Upon completing the plant design, Hitachi drew upon its collective strengths and latest technologies to develop these components.
That is, by introducing the large-capacity, coal-fired boiler — which can handle many varieties of coal and meet the optimum steam conditions through increased pressure and temperature — and the highefficiency steam turbine, both plant efficiency and reliability have been improved.
Furthermore, a newly developed remote-monitoring system installed in the central control room of the plant utilizes expanded-display devices [large-size LCD (liquid crystal display) displays] and wider-scope operation by means of highly functional CRT (cathode ray tube) displays.
As a result of this system set-up, plant operation in terms of labor saving and monitorability is improved.
In addition, the remote-monitoring system is directly connected to the switchgear for auxiliary electrical equipment; consequently, the amount of cable materials used is reduced and the construction cost is lowered.
