Case introduction

ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.

These remarkable advantages have made ZOZEN the gas-fired steam boiler supplier of Zhejiang Qianxilong Special Fiber Co., Ltd., which provides stable steam support for the extraction and drying processes of the fiber manufacturing. Qianxilong Special Fiber is a high-tech enterprise invested and established by Qianxi Group in 2009. It specializes in R&D, production and sales of ultra-high molecular weight polyethylene fiber products (also known as high-strength PE fiber), which is one of the three high-tech fibers in the world today. It is widely used in defense military equipment, aerospace, cable, medical equipment, building materials and other fields. ZOZEN WNS series condensing gas-fired steam boiler has become the important equipment of the Qianxilong Special Fiber production line.
