Jenbacher gas engines provide cleaner, more reliable powerTwo Jenbacher J320 gas engines from GE’s Distributed Power business, working in tandem with an absorption chiller, have given Indonesian textile manufacturer WinnerSumbiri Knitting (WSK) a more cost-effective, effi cient and lower-emissions power supply.

WSK is a leading manufacturer of fabric and textiles for the garment industry, producing over 1.2 million meters of high quality fabric each month. Headquartered in Indonesia, the company uses some of the most sophisticated and modern knitting machineries, as well as advanced capabilities in dyeing, fi nishing and printing facilities. Due to WSK’s rapid growth in recent years, its facilities now run for 24 hours each week day and require new infrastructure to support the expanded operations, including new energy effi ciency needs.

GE’s gas engines, installed in 2007, each supply about 1 MW of power and have more than 60,000 combined hours of successful operation. Prior to installing the engines, WSK had been experiencing production diffi culties because their old power supply was unstable and costly. In addition, WSK had been using older diesel generators for intermittent onsite power needs that were less friendly to the environment and also less effi cient.

KEY TECHNICAL DATA

Number and type of GE units 2 x GE J320 gas engines; 1 x absorption chiller

Generating capacity ~2 MW

Electrical effi ciency Up to 70 percent

Commissioning 2007 (engines); 2009 (chiller/CCHP)

The solution: cogeneration technologyWSK opted for GE’s natural gas solution to power its factory, and two years later, the effi ciency of the Jenbacher units was augmented by installing an absorption chiller that created a true cogeneration plant, also known as: Combined Cooling, Heating and Power (CCHP). The chilled water from the cooler offsets the extremely harsh, warm Southeast Asian climate by cooling the manufacturing hall, which preserves the quality of the knitting equipment and the manufactured goods themselves.

The Jenbacher gas engines now run 24 hours a day, seven days a week, in order to sync with the factory’s operating schedule. Since the electrical needs of the facility are only about 1.3 MW, WSK usually runs one engine at a time. This protects the engines from overuse and assures that excess power capacity is available when needed. In addition to that, WSK recovers 450 TR (~213.75 kW) of chilling from the waste heat of the gas engine and the peak boiler. This means a great cost saving, since almost a half of their power needs are covered by the CCHP technology.
