Metso Automation - 06.25.2007

Agios Dimitrios Power Station, the largest coal fired power plant in Greece (owned by PPC – Public Power Corporation), is replacing the old control systems for unit III and unit IV with new metsoDNA control systems. Metso Automation's delivery includes the automation and information management systems for the two units together with control room equipment, large screens, boiler protection systems, instruments (e.g. transmitters), actuators and annunciators. Metso Automation will also deliver the control system for the flue gas heat recovery system. The start-up of unit IV is planned for end of 2007 and the start-up of unit III is expected to take place in spring 2008.

The Agios Dimitrios Power Station is located 140km west of Thessaloniki in the northwestern part of Greece. The thermal power plant consists of 5 units with a total capacity of 1,600 MW. The electrical output of unit III & IV is 310 MW each. These two units have been in operation since 1985/1986. Each boiler is a once-through boiler, Sulzer type. Steam production is 890t/h at 172 bar, and 810t/h reheat steam at 40 bar/542°C. The steam turbine is a single shaft 3-cylinder (HP/IP/LP) turbine with nominal speed of 3,000rpm. For the production of electricity, the steam boilers are fired with lignite (nearly 550 t/h with a calorific value of ~1,300 Kcal/kg).
