7th for paper mill, ZOZEN effectively controls natural gas boiler prices

7th for paper mill, As an independent national brand whose products have been exported to more than 100 countries and regions, ZOZEN Boiler has set the international quality standards for itself from the beginning. Standardized production process and complete quality management system have enabled ZOZEN Boiler to successfully obtain international authoritative certifications such as ASME (USA), PED (EU) and DOSH (Malaysia), and also win the recognition of ZOZEN’s boiler quality from customers around the world.

7th for paper mill, The SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.

The furnace of ZOZEN’s SZL series coal-fired boiler adopts a closely arranged water-cooled wall tube structure, which effectively prevents the erosion and radiation of high-temperature flue gas for the furnace. The furnace has large radiation area, small maintenance workload and light overall weight. In order to improve the coal applicability of industrial boilers, ZOZEN Boiler designs adiabatic furnace, water-cooled furnace, adiabatic arch, water-cooled arch, etc., and chooses different furnace structures according to calorific value, volatile content and coking characteristic index of coal provided by customers.

This is a membrane wall production line of ZOZEN Boiler. All the membrane walls inside the boiler are produced from here. The steel pipes pass through the polishing equipment and are reduced to the original metal color. Then they will enter the large-scale automatic welding station together with the flat steels that are cut beforehand. This welding station is as high as 4.6 meters with a covering area of 32 square meters. It is equipped with 16 welding guns which can complete the welding of 4 groups of membrane walls at the same time. The welding speed and precision are at the leading level in the industry. Finally, the welded membrane walls are made into various shapes by the pipe arrangement machine.

7th for paper mill, In order to meet the requirements of energy saving, environmental protection and sustainable development, Hubei Guoan Energy Power Equipment Engineering Co., Ltd. needed to purchase eco-friendly gas-fired boilers. After learning about the outstanding comprehensive competitiveness and good market reputation of ZOZEN Boiler, it reached the cooperation with ZOZEN Boiler. According to the actual demands of Hubei Guoan, ZOZEN Boiler recommended the SZS series condensing gas-fired boiler. This type of steam boiler adopts the large-volume furnace and advanced burner to ensure the sufficient fuel combustion and improve the fuel utilization. With the energy-saving devices added at the end of the flue gas duct, the boiler thermal efficiency can reach more than 98%, so as to save the operating costs.

7th for paper mill, The two sides cooperated well for the steam boiler project in Bangladesh. ZOZEN will continue to provide high quality products for the global industrial boiler market in the future.
