ZOZEN SZS series double drum vertical gas-fired watertube boiler is a typical medium and large-sized gas-fired boiler, with a capacity of 20-110t/h and a pressure of 1.25-5.3MPa, which meets the needs of steam and heating for most enterprises. According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the video shows the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
Convection bank tubes connect the upper drum and lower drum in bi-drum boilers. These bank tubes not only act as raisers and down comers between the drums but also carry the weight of the bottom drum in the case of top drum supported boilers.
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.
Automation and digital equipment are widely used in boiler production in ZOZEN Boiler Modern Production Base, which can reduce manual errors and improve the quality of boiler production. Automatic welding technology in boiler drum and steel pipe is used for welding. Welding current, welding voltage, wire feeding speed and walking speed are all fixed parameters, which greatly reduces the influence of human factors on boiler quality and ensure the welding quality.
According to the new staff training system of ZOZEN Boiler, the new round of the boiler room site training has begun. Guided by Mr. Lu Xing, the sales manager of ZOZEN Boiler, the new staffs of ZOZEN Boiler went to the boiler room of one customer, to visit and learn how the boiler operating in the actual situation. The purpose of boiler room visit is to strengthen the knowledge and to better understand the relevant work contents.
ZOZEN Boiler provided a set of reliable steam boiler for the newly built biomass power generation project of BİYOSAN ENERJİ ÜRETİM DANIŞMANLIK A.Ş., a famous local biomass energy production company. The boiler equipment accelerated the construction of a green and low-carbon recycling economic system for users. ZOZEN SZL series biomass-fired boiler supplied steam for this project. The boiler is shipped with the shop-assembled structure, which is composed of two parts: the combustion chamber and chain grate. According to the characteristics of different biomass fuels, the height of combustion chamber can be appropriately increased.
ZOZEN Boiler provided several sets of gas-fired steam boilers to the distributed energy resource park in Jiangsu Province, China. This industrial park used steam boilers for power generation and heating supply for the auto tyre producer. Therefore, ZOZEN Boiler customized several sets of boilers with different parameters to this project.
At the beginning of the 14th Five-Year Plan air pollution prevention and control work, as a large-scale industrial boiler manufacture, Wuxi ZOZEN Boiler Co., Ltd. has received a great amount of orders. The workshop is inspired by the good performance, the frontline workers are working hard and strive to complete the order task with good quality and quantity.
