In September 2007, Wuxi ZOZEN boiler Co., Ltd. has passed theassociation certification, becoming another full-cover power boiler, pressurevessel and pressure components external piping factory manufacturing andon-site installation of ASME companies in Jiangsu Province. This certificationpaved the way for ZOZEN boiler Co., Ltd. to undertake overseas boiler andpressure vessel production and installation projects.
In this review, the ASME Association Joint Inspection Team conducteda rigorous assessment of the forensic review and procedural code standards forthe design and manufacture of power boilers, pressure vessels, and pipelinemanufacturing and installation of Wuxi ZOZEN boiler Co., Ltd., the level of welders,quality system, basic facilities and other achievements have been given a highdegree of evaluation.
Two months later, with the successful operation of the WNS seriesboiler in Colombia, it marked that ZOZEN boiler Co., Ltd. has further developedthe international market. WNS series horizontal internal combustion boiler is athree-way wet back gas (oil)-fired boiler with shell and back designed by ourcompany according to domestic and foreign advanced technology and experience.After the fuel is atomized by the burner, the formed torch is filled in thefull-wave furnace and transmits radiation heat through the wall of the furnace.This is the first pass. The high-temperature flue gas generated by the combustionconverges in the reburning chamber and turns to the second pass, which is thethreaded pipe bundle area. After the convection heat transfer, the flue gastemperature gradually decreases to the front smoke box, and it turns to thethird return. That is, the beam bundle area, and then into the chimney afterthe inspection box, and finally discharged into the atmosphere. This series of boilershave the characteristics of safety, reliability, high efficiency, energysaving, environmental protection, convenient maintenance, durability, automaticintelligent control etc. All performance indicators were higher than the designrequirements.
