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 base of ZOZEN Boiler creates strict production procedure, each performs its own functions. The painting workers are responsible for the boiler painting, while the welding workers are cooperating with each other to do the welding work.
ZOZEN WNS series oil-fired and gas-fired boiler is designed with large-diameter corrugated furnace and threaded smoke tube, which makes the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach over 98%, which is well received by the market.
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 manufacture of a high-quality industrial boiler requires many important links such as blanking, welding, assembly and inspection. In the busy production workshop of ZOZEN Boiler, the frontline workers of ZOZEN Boiler perform their duties and cooperate with each other.
As a member of ZOZEN Boiler, the after-sales personnel goes deep into the boiler room of customers to do debugging and maintenance. Sometimes, in order to satisfy the production needs of users, the after-sales team of ZOZEN Boiler carries out debugging work overnight, catching up with the progress and providing after-sales service wholeheartedly.
All employees of ZOZEN Boiler have established a good quality consciousness of zero defect and continuous improvement, and have practiced in the whole process of boiler design, technology, production, equipment and inspection.
In the long-term production and operation, ZOZEN Boiler always pays attention to the renewal of process equipment and continuously improve the quality and performance of various series of boiler products. 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 accuracy, good repeatability and numerical control programming. In addition, it also has the advantages of faster processing speed and higher accuracy. The accuracy of cutting steel plates can be controlled within 1 mm, which effectively improves the welding and assembly quality of boilers.
