Marubeni Corporation has awarded a contract to refurbish two boilers at the Suralaya steam power plant on Java, Indonesia to Babcock & Wilcox Power Generation Group Inc (B&W PGG).

Under the contract, B&W PGG will refurbish the radiant tower-type boilers at units one and two of the Suralaya plant, increasing the capacity of each unit from 400 MW to 440 MW. Japan-based Marubeni is the prime contractor on the refurbishment project.

B&W PGG will redesign and supply the superheater and reheater surface, low NOx combustion systems, pulverizer performance enhancements and other boiler upgrade equipment. The plant’s existing boilers were originally designed and supplied by B&W in the early 1980s.

The seven-unit Suralaya plant is owned by Indonesia’s government run utility PLN, which is overhauling the 3400 MW coal-fired plant to extend its life, improve efficiency and reduce emissions.

B&W PGG has started engineering and expects to deliver the equipment in late 2009 and early 2010. Unit one is scheduled to go on-line in late 2010, followed by the second unit several months later.
