ZOZEN Low-energy Horizontal Fire-tube Boiler Supports the Sanitary Industry

Boilers are widely used in daily production and life of enterprises. For users, how to correctly choose boiler products suitable for their actual conditions is very important.

ZOZEN WNS Series gas-fired boiler for Huida sanitary

In-depth Introduction to ZOZEN Horizontal Fire-Tube Wet Back Gas-Fired Boiler

WNS Series gas-fired boiler adopts the horizontal wet back structure, with threaded smoke tube to enhance the heat transfer. The triple water level safety control ensures the safe and reliable operation of the boiler.

Energy-saving devices with different configurations can be selected to set at the end of the flue gas duct according to different processes, which can improve the overall boiler thermal efficiency to 98% and above. ZOZEN WNS series gas-fired boilers are stably running on the production lines of leading enterprises in various industries, such as Mengniu, China National Pharmaceutical Group Corporation and Huida Sanitary etc.

ZOZEN WNS gas-fired boilers have a wide range of applications

WNS series gas-fired boiler has large volume with long setup time, therefore, the technicians hoped to use the vertical water tube boiler with shorter setup time. However, the shortcomings of the vertical water tube boiler are also obvious: 1. Small water volume with shorter service life. 2. It is relatively compact without complete energy saving equipment, and has low thermal efficiency, which cannot play a good role in energy saving and environmental protection. 3. The vertical water tube boiler has high requirements for the water quality which cannot be satisfied by normal water softeners. 4. It has potential safety hazard. Once the volumetric heat load of the vertical water tube becomes large, it may result in deterioration of heat transfer, which can cause tube explosion, fatigue crack and other failures.

ZOZEN Horizontal Fire-tube Boiler is More Energy-efficient with 68.2 m³ Gas Consumption Per Ton of Steam

Huida Sanitary once considered to introduce the vertical water tube boiler, however they found it that although the vertical water tube boiler starts up quickly, it has extremely high requirements on water quality, which may lead to many problems such as high treatment and maintenance cost, short service life, which does not conform to the development concept of enterprise.

ZOZEN horizontal gas-fired boiler has large water capacity and good heat preservation effect, and the boiler water is in a high temperature state for a long time, so the restart time is greatly shortened. In addition, combining the existing condensing water recovery system of Huida, ZOZEN Boiler also equipped the boiler with a flue gas recovery device with economizer and air preheater at the end of the boiler, which can save 2m³ natural gas per ton of steam produced, which not only saved investment but also improved boiler thermal efficiency, so as to successfully won the high praise of Huida Sanitary.

Actual operation data of ZOZEN gas-fired boiler

After the project was put into production, according to the monitoring data, ZOZEN gas-fired boiler produced 1,682 tons of steam and consumed 114,700 Nm³ of natural gas in one month, that is to say, the actual gas consumption per ton of steam was only 68.2 m³. Compared with similar products in the market, the fuel cost could be saved by nearly 400,000 yuan per year, which achieved a win-win situation for environmental protection and economic development of enterprises.
