ZOZEN Boiler provided an energy-saving and environment-friendly WNS gas-fired steam boiler for a food enterprise in Suzhou. The gas-fired steam boiler adopts two-pass design, and the use of large-diameter corrugated furnace and threaded smoke tube make the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach more than 98%.
Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding.
According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. 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. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the photos show the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
Before delivery, ZOZEN gas-fired fire tube boiler shell is covered with the stainless steel film to prevent damage to the boiler shell in the process of transportation and installation. The film will be removed after installation. The mirror stainless steel shell of the boiler has the features of low heat loss and beautiful appearance. The pictures show the blank pressing process of the stainless steel materials, which is the previous process of installing the stainless steel film, this process aims to make the material seam much flatter and firmer where surfaces intersect and meet.
Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding. In the production base of ZOZEN Boiler, a professional boiler manufacturer, front-line welders are ensuring the quality of boiler welds with superb technical level, lofty ideological awareness and strong sense of responsibility.
The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.
The production of a set of high-quality industrial boiler includes many important processes such as blanking, forming, welding, flaw detection, hydrostatic test and so on. ZOZEN front-line workers performed their own duties and cooperated with each other to complete the boiler production and ensure the quality of each set of boiler at the same time.
At the 150,000-square-meter production base of ZOZEN Boiler, ZOZEN foreign trade sales manager was conducting live broadcast with Thailand's customers. Through the mobile phone network, ZOZEN showed the CNC blanking, CNC plate rolling, longitudinal and circumferential welding production lines to Thailand’s customers. In the blanking workshop, ZOZEN CNC vertical lathe was beveling the boiler drum heads with high processing precision, which can effectively improve the production efficiency and overall processing level of boilers.
