In the railway system, industrial boilers play an important role in the heating of railway stations and locomotive depots. Aa a leading industrial boiler manufacturer, ZOZEN has provided more than 170 sets of boilers for 9 railway bureaus including Beijing Railway Bureau, Lanzhou Railway Bureau and Harbin Railway Bureau. With stable operation and high-efficient performance, the boilers are well received by users.
Zhengzhou Railway Station is one of the eight transportation hubs in China. Integrating high-speed railways, intercity railways, EMU trains and regular-speed trains, the station is known as the heart of China’s railways. In addition, Zhengzhou Station is at the intersection of multiple railway lines, trains from here can get to any capital city in China, even can directly get to Hong Kong.
With stable and high-efficient operation, ZOZEN SZS series gas-fired boilers provided passengers with comfortable waiting environment. This series of boiler adopts an advanced automatic control system, the boiler operator can realize the start-stop, load adjustment, and automatic water supply operations of the boiler by easy setting. Apart from easy operation, ZOZEN also adopts various interlock protection functions to ensure the safe and reliable operation of the boiler.

In the entire railway system, apart from the railway stations in each region which are considered as important nodes, the 69 locomotive depots under the jurisdiction of the railway bureaus are the main driving departments in the railway transportation system. The locomotive depots are responsible for the use of locomotives, comprehensive maintenance and overall maintenance. In recent years, with outstanding product advantages and strong enterprise strength, ZOZEN has provided high-efficient and energy-saving gas-fired boiler systems for many locomotive depots.
In the three years from 2017 to 2019, ZOZEN had completed the manufacturing and installation of 16 sets of gas-fired boilers for Urumqi Railway Bureau. During this period, the Hami Locomotive Depot removed 3 sets of coal-fired boilers from the Hami Maintenance Workshop of the West Depot. And, ZOZEN successfully completed the installation and commissioning of the WNS series gas-fired steam boilers within the agreed time. The boilers became important heat source of the locomotive depot.

ZOZEN WNS series gas-fired boiler has a compact structure. The boiler is stable and reliable. It adopts a large-diameter corrugated furnace to ensure sufficient steam storage space and heating area. The heat transfer coefficient of threaded flue tubes is 1.2 times higher than that of ordinary flue tubes. Besides, energy-saving devices were equipped at the tail of the flue to improve the inlet water temperature, reduce the exhaust gas temperature and increase the thermal efficiency to more than 98%, which realized the goal of energy saving and emission reduction for many locomotive depots.
The railway system has played a strong supporting role in the development of economy. ZOZEN has also provided stable and high-efficient boilers to the huge railway system. In the future, ZOZEN will strive to provide solid support for the smooth operation of the railway network.
