The stability of the boiler operation will directly affect the quality of the product. Therefore, Dalishen set high requirements for the stability of the pressure and temperature of the gas-fired boiler. ZOZEN customized the WNS series natural gas steam boiler solution according to the actual heat requirements of Dalishen. This series of steam boiler is a two-pass boiler. The use of a large-diameter corrugated furnace and threaded smoke tubes improves the heat transfer efficiency. In addition, ZOZEN adopts energy-saving devices such as the condenser at the end of the flue to increase the boiler thermal efficiency to over 98 %. Meanwhile, the stable operation of the WNS series gas-fired boiler comes from the high quality of the boiler itself. As a leader of industrial boiler manufacturers, ZOZEN has 600 sets of advanced numerical control facilities and the blanking CNC rate has reached over 80%, which not only ensures the processing accuracy of the boiler components but also reduces assembly stress and prolongs the boiler service life. Besides, the advanced submerged arc automatic welding technology ensures the welding quality. And, a 100% radiographic inspection is carried to every longitudinal and circular seam to ensure the boiler quality.
Founded in 2007, Jiangsu Dalishen Science &Technology Co., Ltd. is mainly engaged in the research, development and production of aluminized zinc (steel coil), color coating (steel coil), high-precision silicon steel plates. With multiple (aluminum) zinc plating production lines, color coating production lines and silicon steel lines, Dalishen has constructed four phases of projects. This fifth phase of the project is a heat supply project for the high-precision silicon steel production lines. A new set of natural gas boiler will be adopted to supply steam for the internal silicon steel production and waste acid treatment.
This ZOZEN WNS series boiler adopted a packaged structure. The boiler was put into trial operation once the pipelines and the auxiliaries were installed at our construction site, which greatly saved the installation costs for our company. We were very satisfied with the boiler.
