ZOZEN Boiler is a professional manufacturer of industrial boilers in China. ZOZEN Boiler entered the boiler industry in 1988 and took root in the boiler industry, always taking manufacturing high-quality boilers as its responsibility. Through the wonderful video, we recorded the ZOZEN people who work hard in the front line of production. They always adhere to the quality and create ZOZEN good-quality boiler products. After years of development, ZOZEN Boiler has won a good market reputation by virtue of its reliable quality and perfect service.
According to the specific conditions of the pulp and paper industry, ZOZEN boiler provides boilers with high combustion efficiency and low operating cost and is recognized by paper enterprises. The advanced boiler automatic controller, man-machine interface, users only need to set easily, the boiler can start and stop, regulate load and according to user requirements, load regulation, automatic water supply and other fully automatic operation.
An air preheater is used to preheat the fuel which further increases the boiler efficiency. It is designed to heat air before another process by extracting the waste heat from the flue gases leaving the boiler to effectively reduce the flue gas temperature and improve the thermal efficiency.
Welding is a vital work in the process of boiler manufacturing, and it has an important influence on the quality of the boiler. In the production base of ZOZEN Boiler, a professional boiler manufacturer, the front-line welders always ensure the quality of the boiler welding seams with their superb technology and responsible attitude. At the same time, ZOZEN Boiler has introduced the advanced welding equipment to realize the welding automation of the main components such as drums, membrane walls, serpentine tubes, steel frames, etc.
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.
The boiler as a kind of common special equipment, the quality, specification and mark of its raw materials should meet the requirements of the applicable material specification. According to the different requirements of various materials purchased, ZOZEN Boiler has established a strict acceptance system to ensure the raw materials in compliance with the material specification and to prevent the unqualified raw materials entering into the production processes. For the safe operation of the boiler, sectional materials will be strictly re-inspected to ensure the boiler pressure strength.
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.
