The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications. Under these conditions, there is a wide range of ZOZEN hot water boiler products available.The after-sales service of boilers is the issues that users are very concerned about. ZOZEN is ...
ZOZEN WNS series gas-fired boiler has a compact structure. The boiler is stable and reliable. It adopts a large-diameter corrugated furnace to ensure sufficient steam storage space and heating area. The heat transfer coefficient of threaded flue tubes is 1.2 times higher than that of ordinary flue tubes. Besides, energy-saving devices were equipped at the tail of the flue to improve the inlet water temperature, reduce the exhaust gas temperature and increase the thermal efficiency to more than 98%, which realized the goal of energy saving and emission reduction for many locomotive depots.
In mid-October, the Service Center of ZOZEN received a call from the customer and reported that the NOx emission from the gas-fired boiler exceeded the standard. This customer is a renowned enterprise in the beverage industry. Its subsidiaries all introduced ZOZEN low NOx steam boilers. The burner of ZOZEN low NOx boiler adopts air partition, fuel partition and flue gas recirculation technologies to achieve low NOx combustion, reduce the combustion temperature in the central flame area while achieving the requirement of NOx emission below 30mg/m3. This should not happen in theory. In this regard, ZOZEN immediately sent professional technicians to the boiler room to check.
In 2002, PT.Lontar Papyrus, which located in Indonesia, bought a 100tph coal-fired steam boiler from ZOZEN. Field-assembled boiler has high requirement for on-site installation. Therefore, ZOZEN negotiated with local experienced PT.ZUG Company and succeeded in achieving long-term cooperation.
