In the corrugated paper processing production line of the packaging industry, the steam boiler is an important heating system to increase the temperature of the cardboard and is one of the indispensable supporting equipment. Fujian Nan’an Lianfa Paper Co., Ltd. was established in 1995. In the more than 20 years of development and growth of the company, it has continued to innovate, pay attention to technology investment, and strictly control product quality. Product quality and economic benefits. Facing fierce market competition and severe environmental protection situation, Lianfa Paper decided to eliminate outdated production capacity and introduce environmentally friendly gas steam boilers with high quality and excellent performance.

　　 After comparative analysis of many boiler products, Lianfa Paper was attracted by the excellent quality performance and environmental protection advantages of Taiguo boiler WNS series gas boiler. In order to ensure the high quality of boiler welding, all longitudinal and circumferential seam welding adopt advanced submerged arc automatic welding technology, and pass 100% radiographic flaw detection to prevent unqualified welds. The design of the large-diameter corrugated bladder of this series of boilers provides sufficient heating surface and steam storage space to ensure the stable and efficient output of high-quality steam. With the addition of energy-saving equipment at the end of the flue, the exhaust gas temperature can be reduced to 60℃ , The thermal efficiency is as high as 98%, and the ultra-low emission of nitrogen oxides can be easily achieved, which improves the economic benefits while taking into account the environmental benefits.
