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, how to build a steam boiler.

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, how to build a steam boiler.

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%, how to build a steam boiler.

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.

Starting from the steel sheet blanking, every key process of ZOZEN adopts advanced CNC processing technology, which ensures the quality of the boiler and shortens the delivery time. Efficient automated production lines, sufficient raw material stocking, and scientific 6S on-site management ensure that multiple SZS series gas-fired hot water boilers are delivered with high quality within the agreed time.

All boilers are subject to damage if proper water treatment procedures are not followed. This is an important consideration both during operation and when the boiler is idle. To avoid damage and costly repairs, monitor water chemistry routinely and ensure that you are supplying your boiler with soft water at all times.
