As a member of ZOZEN Boiler, the after-sales personnel go deep into the boiler room of customers to do debugging and maintenance. Sometimes, in order to ensure users' production needs, they do debugging work overnight to catch up with the schedule.
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.
The large-scale fiber laser cutting machine being developed by ZOZEN Boiler is similar to the existing plasma cutting machine, and has the characteristics of high precision, good repeatability, numerical control programming and so on. Besides, it has the advantages of faster processing speed and higher precision. The accuracy of cutting steel plates can be controlled within 1 mm, which effectively improves the welding and assembly quality of boilers.
As a professional industrial boiler manufacturer, ZOZEN Boiler has always maintained the advanced technology and equipment. It owns 600 sets of advanced production equipment in the industry, with high processing precision and high efficiency, guaranteed boiler quality, and realized large-scale production with short delivery period.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
ZOZEN Boiler has cooperated with the Department of Thermal Engineering of Shanghai Jiaotong University to jointly develop the DZL series tri-drum biomass-fired boiler. This kind of steam boiler is a water tube boiler adopting the assembled structure with two parts. The boiler can be equipped with different grates to ensure the sufficient combustion of biomass fuels.
ZOZEN Boiler recently provided boilers for several industries, for instance. the construction material factory, the heat supply industry, the chemical industry and the textile industry, etc.
ZOZEN will test the leak-proof air pressure of every set of SZS series boiler before delivery. Poor tightness will lead to the leakage of gas fuel, which will not only affect the safe operation of boiler, but also increase the heat loss. The leak-proof air pressure test can secure the tightness of each SZS series gas boiler.
