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.
In the modern production workshop, the fully automatic production line is a powerful guarantee for the efficient operation of ZOZEN Boiler; the orderly production site is the effective result of 6S management; and the cautious and conscientious work style and continuous innovation and search attitude of ZOZEN people is the backbone of the whole enterprise.
ZOZEN WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace and threaded smoke tube to increase the heating surface, reduce the thermal stress and improve the boiler's safety performance; meanwhile, in order to reduce the heat loss caused by gas exhaust and operating costs, ZOZEN also adds energy-saving devices at the end of the flue gas duct to improve the thermal efficiency to over 98%. In addition, the two sets of boilers also meet the ASME standards, which proves that ZOZEN product quality is up to international standards.
Boiler is an important part in the social production field. The boiler production should be more scientific and professional. Welding is a very important step in the production of boilers and welding technology in the boiler manufacturing process is also related to other manufacturing industries in any country. ZOZEN has always encouraged the front-line welding workers to improve their skills and quality to improve the welding technology of ZOZEN Boiler.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
The ZOZEN 4 tph WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace, which increases the heat transfer surface, reduces the thermal stress and improves the boiler safety. Meanwhile, in order to reduce the heat loss due to exhaust gas and operating costs, ZOZEN also installs the energy-saving equipment at the end of the flue gas duct to ensure boiler's thermal efficiency reaches 98% and above. What's more, WNS series boilers also have the characteristics of fully automatic intelligent control and easy operation to ensure boiler's long-term, safe and stable operation, so they are well received by users at home and abroad.
A set of industrial boiler with sufficient output and stable heating supply can directly affect the daily production of a food company. ZOZEN DZL series biomass-fired steam boiler adopts the single-drum longitudinal layout and chain grate stratified combustion method. ZOZEN technicians has optimized the design of the feed hopper, grate width and length, speed of grate reducer and position of secondary air outlet by analyzing the different fuel characteristics and practical use requirements of customers to ensure the sufficient combustion of biomass pellets and improve the combustion efficiency. Meanwhile, DZL series biomass fired steam boiler adopts the thread smoke tubes developed by ZOZEN to strengthen the heat transfer and improve the thermal efficiency. The heat transfer coefficient of thread smoke tube is 1.8 times higher than that of ordinary smoke tube and the thermal efficiency of boiler is over 88%, which can fully meet the daily production demands of enterprises.
The welding of horizontal fixed tubes is to weld the tubes which are put in the horizontal or nearly horizontal position. This kind of welding includes three spacial positions: upright, vertical and horizontal (all-position), which puts forward high requirements for the welding technology. Facing the difficulties brought by welding appearance requirements, curvature of tube joint, and small tube diameter, ZOZEN workers are skilled in welding to ensure the welding quality to effectively extend the service life of boilers.
