ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.
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.
ZOZEN’s WNS series fire tube boilers are favored by SOORTY in Pakistan with the energy conservation and environmental protection characteristics. Therefore, ZOZEN successfully cooperated with SOORTY.SOORTY is one of the largest vertically integrated denim manufacturers from Pakistan. It produces denim fabrics and jeans for brands such as H&M, ZARA, Calvin Klein, etc.. Production capacity of 2.5 million garments per month makes them leader of the league. Steam boilers play an important role in the process of dyeing, steaming and printing. With increasing demand in international market, SOORTY, which believes that sustainability is a lifestyle, decided to add a new environment-friendly steam boiler. After comparing many steam boilers from kinds of boiler manufacturers, SOORTY preferred ZOZEN’s WNS series fire tube boilers, which meet all the needs of SOORTY.ZOZEN provided SOORTY with one set of WNS series fire tube boilers according to ASME standard. This kind of fire tub
One set of 40 tph gas-fired water-tube boiler is successfully shipping to Turkmenistan within a relatively short period, which is filled with the efforts of all staff.
The kind of gas-fired steam boiler is designed to help a large refinery in Turkmenistan reduce the energy consumption while ensuring production line running smoothly. The steam is used for oil refinery processes, including crude distillation, thermal cracking, catalytic cracking and purification. Based on the actual requirements, ZOZEN has provided a 40 tph tailored-made gas-fired steam boiler for the refinery. The boiler features high efficiency and low consumption. The furnace is large and the heating surface is sufficient, which can make the fuel fully burned. The thermal efficiency can reach above 98%.
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.
