Raozan Power Station

Raozan Power Station is a gas-fired thermal power station in Bangladesh. It is located in Raozan Upazila of Chattogram District 25 km north-east from Chattogram on the south side of the Chattogram–Kaptai Highway. It is owned and operated by the state-owned Bangladesh Power Development Board.

History
Construction of the power station started on 1 February 1990 and the first unit was commissioned on 31 July 1993. It was constructed and credited by the China National Machinery and Equipment Import and Export Corporation.

Technical features
The power station consists of two identical gas-fired units with an initial capacity of 210 MW and a generating capacity of 180 MW. It is supplied from the Bakhrabad and Feni gas fields, and from the Sangu offshore field.

The N210-12.9-538/538 super high-pressure intermediate reheat condensing, three-cylinder double exhaustion turbo set turbine, installed at Unit 1, was manufactured by Dong Fang of China. It has a rated capacity of 210 MW and a normal speed of 3,000 RPM. The steam flow at the rated parameter at full load is 652.5 t/h at the temperature of 538 °C with a live steam pressure of 12.9 MPa. The turbine was delivered in July 1991.

The boiler is a DG-680/13.7-14 type of super high pressure, one intermediate re-heat cycle and single drum natural cyclic type boiler manufactured by Dong Fang of China. It has a steam generating capacity of 680 t/h generating 541 °C 13.73 MPa pressured steam at the boiler outlet. At full load, it consumes 52695.4m3/h of natural gas. The efficiency of the boiler is rated at 94.93%. Transformers are manufactured by Shen Yang of China.
