4000kg steam boiler coal fired, ZOZEN boiler, the grade-a boiler manufacturer, success fully passes the renewal audit of grade-a boiler manufacturing license

4000kg steam boiler coal fired, As an industrial boiler manufacturing company with more than 30 years of development history, ZOZEN today's achievements are inseparable from its sustainable development concept.  Recently, ZOZEN reached cooperation with Libbey Inc., the global glassware industry giant. The two sides shared the same development concepts and became friendly and trustworthy partners.

During the "Thirteenth Five-Year Plan" period, China's oil refining industry will focus on transformation and upgrading, and continue to enhance comprehensive strength. It will vigorously eliminate backward production capacity and improve the scale and technology of its units. Among them, the boiler as an important piece of energy equipment is indispensable in the petroleum refining process.

ZOZEN WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. It uses threaded smoke tube for heat transfer and manages to achieve a thermal efficiency up to 98%. The economizer is installed at the tail of boiler, giving the boiler a compact size. Meanwhile, sound automatic control system enables unattended operation.

ZOZEN 4 tph WNS series oil-fired fire tube boiler for construction industry in South Africa. Pholaco is a construction materials company specializing in light steel frame (LSF) construction, EPS panel construction, and CLC (cellulose lightweight concrete) construction. ZOZEN provided 4 tph WNS series heavy oil fired boilers for the company. This kind of fire tube boilers adopt large corrugated furnace for full fuel combustion. In combination use of the thread smoke tubes, the thermal efficiency is up to over 98%.

4000kg steam boiler coal fired, ZOZEN WNS series gas fired boiler not only adopts advanced low NOx burners. And through the flue gas recirculation technology, about 10% -30% of the flue gas at the tail of the boiler is sucked into the air inlet of the burner through the flue gas pipe, mixed with the combustion-supporting air, and then entering the furnace, thereby reducing the temperature and oxygen concentration in the combustion area, and finally reducing The amount of thermal NOx is generated, and the NOx in the tail gas of the boiler are less than 30mg/Nm3, which meets the requirements of low nitrogen emissions of the enterprise.enterprise.

ZOZEN technicians made professional records of maintenance

4000kg steam boiler coal fired, In terms of pre-welding treatment, ZOZEN can be said to keep improving. The three processes of grinding and rust removal, edge milling, and vertical chamfering eliminate a large number of blowholes in the weld and ensure welding quality.

It’s critically important to stay in lock step with your customers to understand how products need to evolve to continue to meet their needs. It’s easy to fall into the behavior of “milking” existing products. Products must continually evolve to remain relevant and useful. The path to success is through continual product innovation. It is the ZOZEN Boiler way.
