Raozan Power Station is a gas-fired thermal power station in Bangladesh. It is located in Raozan Upazila of Chattogram District 25 kilometres (16 mi) 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.^[citation needed] It was constructed and credited by the China National Machinery and Equipment Import and Export Corporation.[1]

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.[2][3][4] It is supplied from the Bakhrabad and Feni gas fields, and from the Sangu offshore field.[5][6]

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 (1,000 °F) with a live steam pressure of 12.9 MPa. The turbine was delivered in July 1991.^[citation needed]

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 (1,006 °F) 13.73 MPa pressured steam at the boiler outlet. At full load, it consumes 52695.4m^3/h of natural gas. The efficiency of the boiler is rated at 94.93%. Transformers are manufactured by Shen Yang of China.^[citation needed]
