3 ton fire tube steam boilers manufacturers, with 30-years innovation, the manfacturing level of ZOZEN boiler is industry leading
The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. NOW, ZOZEN will help introduce the economizer. The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases the exhaust that leaves the boiler stack.
ZOZEN DHL series coal-fired water tube hot water boiler is popularized and applied in Liaoning Province, and is also an ideal heating equipment for central heating.
ZOZEN SZL series coal-fired steam boiler is package or shop-assembled water tube boiler with double-drum and chain grate structure.Boiler with capacity of 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment.
3 ton fire tube steam boilers manufacturers, As a provider of overall solutions of industrial boilers, ZOZEN Boiler has comprehensive boiler products to better meet the customer demands. ZOZEN uses the professional technology which covers the whole production process of industrial boilers from research, design, equipment supply, construction, after-sales service, spare parts supply to customer training in order to create greater values for 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.
According to the actual production demands of Lenzing (Nanjing) Fiber Co., Ltd., ZOZEN Boiler recommended the SZS series gas-fired superheated steam boilers. This series of steam boiler adopts the large-volume furnace to ensure the sufficient fuel combustion. Combined with an advanced low-NOx burner, it can easily achieve the low emission of NOx, which meets the environmental protection requirements of Lenzing Group. At the same time, in order to improve the boiler thermal efficiency, it not only uses the high-quality aluminum silicate fibers for the furnace body, but also uses high-temperature refractory mud for heat preservation. With the additional energy-saving equipment at the end of the flue gas duct, the boiler thermal efficiency is as high as 98% to save the operating costs.
3 ton fire tube steam boilers manufacturers, 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.
