FGD in Power Plant Tanjung Bin in Malaysia

2100 MW new coal fired power station in Malaysia uses Pennguard lined steel chimney flues downstream of its FGD systems.

With its growing economy and a population that is expected to reach 29 million in 2010, Malaysia is experiencing a continuous, strong increase in its electrical power consumption. To keep up with electricity demand, 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 southwest of the Malaysian peninsula.

Before the construction of Tanjung Bin Power Station could even start, the owner had to perform great improvements to its 70 hectare piece of land. To improve on the swamplike conditions, he used some 6 million cubic metres of sand. A further 2.3 million cubic metres of clay were removed to create an 18 m deep harbor for bulk carriers bringing in imported coal. Throughout design and construction, the owner was supported by German engineering company Fichtner.


The construction of the three 700 MW power units 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.

Sea Water FGD

The 700 MW units of Tanjung Bin Power Station are equipped with a Sea Water FGD system to allow the station to fire a range of coals while observing the Malaysion emmisions limit for sulphur dioxide. 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. However, when low sulphur coal is available, the operator has the option to fully bypass the FGD system. In that case, the flue gas exit temperature is 135-140 °C.

Tanjung Bin Power Station has a 200 m high reinforced concrete chimney with three, 7.5 m net diameter steel flues. To protect these flues against a very corrosive and variable operating regime, they were contructed with the PennguardTM Block Lining System applied over the full height of their internal steel surface. In total, the three chimeny flues use 13,037 m² of PennguardTM linings.
