Through the wonderful video, we recorded the ZOZEN people who worked hard in the front line of production. They always adhered to the quality and created ZOZEN high-quality boiler products. After years of development, ZOZEN Boiler has won a good market reputation with its reliable quality and perfect service.
Our company is a domestic enterprise integrating boiler design, manufacture, sales and service. 600 sets of advanced manufacturing equipment, such as CNC tube bending machine, CNC drum drilling machine and automatic welding in drum, have greatly improved the production efficiency and quality. Thanks to the implementation of lean production projects, all employees of the company have established the awareness of good quality.
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.
The excellent quality of ZOZEN Boiler comes from every working procedure. A convection tube bundle consisting of thousands of tubes is arranged between the upper and lower drums of SZS gas-fired boiler, and each tube should be welded with the drum with high quality to ensure tightness and no leakage. In this part of the work, it requires a large amount of welding with strict requirements, and the welding operation condition is tough. However, the employees of ZOZEN frontline cooperate with each other to ensure the efficient and orderly welding of convection bank tubes.
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.
Boiler drum is one of the important components of boiler body, and its manufacturing requirements are strict. As a powerful boiler manufacturer, ZOZEN Boiler introduced advanced plate rolling equipment while standardizing the plate rolling process, to ensure better quality of the boiler drum. In the modern workshop of ZOZEN Boiler, the steel plate after pretreatment such as derusting, milling and chamfering will be transported to the drum workshop, and then rolled into the workpiece for manufacturing drum by the advanced four-axis numerical control bending machine.
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.
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.
