The gas fire tube boiler is preparing for the painting after the processes of blanking, welding, assembling and packaging. ZOZEN Boiler stipulates strict standard on the painting process. The puttying in the painting process is one of the key steps, the purpose of puttying is to fill or clear the uneven part of the base surface.
The oil boiler of ZOZEN Boiler is called the WNS series. It is a popular boiler system that is received by many users in all kinds of industries. For the oil fire tube boiler, it has the advantages of high safety and efficiency, a good performance of energy conservation, also it is easy to maintain, and the automatic control system is equipped to improve the operation efficiency.
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.
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.
Recently, the spot supply of ZOZEN gas-fired boiler solved the urgent problem of the unstable steam supply of biomass gasification boiler during the upgrading and reconstruction of the central heating project. ZOZEN SZS series gas-fired boiler of this tonnage is mainly composed of boiler body, connecting smoke tube, burner, steam-water system, instrument, economizer and condenser. The boiler system has the characteristics of high thermal efficiency, sufficient output, green combustion, pollution-free emission and fully automatic operation.
ZOZEN WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas-fired boiler. Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power the stress and expand boilers working life.
The new customized type of ZOZEN SZS series oil/gas-fired boiler is now available on the website. The new appearance of SZS series acquires the patent No. CN202030030831.X with the good performance of anticorrosion. Also, the well-structured 'D' type chamber with large volume design ensures the sufficient combustion and good airtightness. The imported low-NOx burner can easily control the generation of the NOx.
Automation and digital equipment are widely used in ZOZEN Boiler to reduce manual errors and improve the production quality of boilers. ZOZEN WNS series gas-fired boilers will go through strict quality inspection procedures before leaving the factory.
