Wuxi ZOZEN Boilers Co., Ltd. is a well-known industrial boiler manufacturer in China. With the excellent product quality and comprehensive sales network, ZOZEN boilers have been sold to many countries and regions around the world. The video shows the waste heat recovery equipment matching with ZOZEN thermal oil heater, which is the energy-saving equipment selected based on the customer’s actual working conditions. The waste heat recovery equipment can make full use of the flue gas waste heat to effectively improve the thermal efficiency of the thermal oil heater.
Heat treatment is an essential part of the manufacturing process, involving heating a metal or alloy to a specific temperature and then cooling it to harden the material. In the manufacturing process of boilers, the following pressure components require post-weld heat treatment: alloy steel pressure components and carbon steel pressure components which include butt joints with wall thickness greater than 30mm, the cylinders of internal combustion boilers, and T-joints with tube sheet wall thickness greater than 20mm. As a professional industrial boiler manufacturer, ZOZEN Boiler always strictly follows the boiler safety technical specifications to conduct heat treatment on specified boiler components, which effectively reduces the residual stresses in the material that have been introduced by welding and improves the boiler performance.
ZOZEN WNS oil-fired and gas-fired boiler is one of the best-selling series of energy-saving and environmental protection boilers in China. The inside of the boiler consists of large diameter corrugated boiler, threaded smoke tube, and other boiler components.
WNS series and SZS series gas-fired steam/hot water boilers are the best-selling products of ZOZEN Boiler, which have the advantages of high thermal efficiency over 98%, emission of nitrogen oxides below 30mg/nm, excellent energy saving and environmental protection performance, and are well received by domestic and foreign markets. The capacity range of ZOZEN gas-fired steam/hot water boiler is 1-110 t/h and 0.7-116 MW, which can meet various production and heating needs of enterprises.
WNS series gas-fired steam boilers customized by ZOZEN Boiler have the advantages of high thermal efficiency, strong environmental protection performance and automatic operation. It is commendable that the WNS series gas-fired boilers adopt the patented appearance of ZOZEN Boiler (patent No. ZL202030031426), which has beautiful appearance and good corrosion resistance.
In the traditional manufacturing industry under the background of the new era, in addition to training the basic skills of manufacturing, the importance of perfect after-sales service has become increasingly prominent, which has become an important factor to open the gap between the same industries. ZOZEN Boiler provides users with reliable after-sales service in all aspects.
In the modern production workshop of Wuxi ZOZEN Boiler, a professional boiler manufacturer, quality inspectors are using professional ultrasonic flaw detectors to inspect the quality of the weld between corrugated furnace and boiler drum; Assembly workers are carrying out pre-expansion, full welding and re-expansion before welding, which not only prevents the crack corrosion between WNS boiler flue pipe and tube plate, but also improves the welding strength; Welding workers are welding the roller automatically.
As a professional industrial boiler manufacturer, ZOZEN Boiler has always maintained the advanced technology and equipment. It owns 600 sets of advanced production equipment in the industry, with high processing precision and high efficiency, guaranteed boiler quality, and realized large-scale production with short delivery period.
