IRPC, the first fully integrated petrochemical complex in Southeast Asia, is located in an industrial area of Rayong, Thailand, with energy and sea port operations to support the area’s businesses. A subsidiary of Global Power Synergy PCL, IRPC Clean Power Company, Ltd., (IRPC CP) owns and operates a cogeneration plant that produces and sells steam and electrical power.
Through engineering, procurement and construction (EPC) contractor TTCL Public Company Limited, The Babcock & Wilcox Company (B&W) was selected to supply IRPC CP’s combined heat and power (CHP) plant, CHP II, with an industrial boiler capable of generating and supplying steam to a neighboring factory. The project required a steam generation solution that could provide five minutes’ worth of water retention in case of a loss from feedwater pumps before a low-water trip to the boiler. Cost, transportation and environmental considerations also factored into the design.
To meet all requirements of a high-capacity, factory built unit, B&W engineered and delivered an elevated three-drum water-tube boiler. It was designed to accommodate ample water holding capacity, much greater than a two-drum design. The large steam drum was mounted prior to shipment, but for instances in which shipping height and weight limitations exist, the steam drum could be transported separately and assembled onsite.
Commercial Operation: December 2016
Manufactured in West Point, Mississippi, USA, the unit was transferred by truck to the Tennessee-Tombigbee Waterway then by barge to a port near Houston, Texas, shipped to IRPC’s dock in Rayong and delivered by truck to the plant.
