Tanjung Bin Power Station
With the strong increase in electrical power consumption in Malaysia, the Malaysian government has allowed private investors to develop several large power stations. The largest of these is the 3 x 700 MW Tanjung Bin Power Station in the state of Johor, in the south west of the Malaysian peninsula.
The construction of the three 700 MW power units at Tanjung Bin Power Station was undertaken by a consortium under Sumitomo and Malaysian company Zelan for all civil works. Turbine, boilers and related electrical and mechanical balance of plant were supplied by Toshiba and IHI. The 700 MW units are equipped with Sea Water FGD. When coal with a moderate sulphur content is fired, about 60% of the gas stream passes through the FGD system and the flue gas exit temperature is 75-80 ˚C (167˚F - 176˚F). When low sulphur coal is fired, the operator can fully bypass the FGD system. In that case, the flue gas exit temperature is 135 - 140 ˚C (275˚F - 284˚F).
To protect the steel flues against a very corrosive and variable operating regime, Pennguard linings were applied over their full height. In total, the three steel chimney flues use 13,037 m2 (140,330 ft2) of Pennguard linings.
The builders of the Tanjung Bin chimney (BEC), chose to install the Pennguard linings in the three steel flues before their erection. The 7.58 m diameter and 6 m high flue sections were grit blasted, primer coated, and Pennguard lined at ground level. Each lined section was transported into the chimney and attached to the chimney flue by bolted flanges. The complete installation process is explained on page 2 and 3 of the Project Report.
Designing chimney flues for optimum long term performance -Pennguard linings are increasingly chosen over any other technology
Owners and constructors worldwide need power station chimneys that will operate under low temperature, corrosive and sometimes variable conditions. In spite of their severe operating environment, these chimneys are expected to perform reliably for many years, with minimal downtime. More and more often, Pennguard lined steel flues are selected as the most effective technology.
Pennguard linings are: practical, durable and reliable. For more information, please take a look at page 4 of Tanjung Bin Project Report.
