Andritz, Austria, has received an order from Nine Dragons Paper Ltd., China, to supply a total of five circulating fluidized bed boilers (Powerfluid) for utilization of in-house residual materials. The boilers will be installed at the company‘s locations in Taicang, Quanzhou, Yongxin, Chongqing, and Dongguan. Startup is scheduled for the second half of 2018. 

Only waste from recycling of wastepaper (rejects, sludges) undergoes thermal utilization, and the high-pressure steam produced is used to generate electricity and supply the Nine Dragons paper mills with process steam. Rejects and sludge are a considerable challenge in boiler operations due to the corrosive substances and impurities they contain, and they require a special design in this regard. 

Nine Dragons Paper is the largest paper producer in Asia and leads the field in resource-saving paper production, observing the most stringent environmental standards. The five plants ordered from Andritz are also designed for significantly lower flue gas emissions than those required by European legislation. The order from Nine Dragons represents Andritz’s return to the Chinese power boiler market after an absence of almost 20 years.
