Fire Tube Boiler Catalogue

Introduction to Fire Tube Boilers
Fire tube boilers, also known as shell boilers, are one of the two main types of gas boilers. In a fire tube boiler, high-temperature flue gases generated by the burner pass through threaded smoke tubes surrounded by water. The heat is transferred to the water, steam, or a mixture of steam and water outside the smoke tube walls, resulting in the generation of steam or hot water.

Introduction to WNS Series Fire Tube Boilers
WNS series is the most popular fire tube boiler you can find in our fire tube boiler catalogue. The WNS series fire tube gas boiler offered by ZOZEN is known for its wide fuel adaptability, capable of using natural gas, biogas, and coal gas. These boilers have a service life of up to 20 years. The threaded smoke tubes extend the residence time of flue gases, enhancing heat transfer and achieving high thermal efficiency, making them energy-efficient and environmentally friendly. You can know more about the WNS series fire tube boilers in our fire tube boiler catalogue.

Features of Fire Tube Boilers:

• High Drilling Precision and Expansion Joints in Critical Areas
  Small-scale manufacturers may struggle to guarantee drilling precision, which is crucial for areas such as high-temperature zones and smokeboxes. Insufficient precision can lead to serious consequences, including cracked tube plates, torn smoke tubes, and water leakage, especially in hot water boilers.
  To address this issue, ZOZEN introduced high-speed CNC flat drilling machines, equipped with a complete set of milling cutters imported from Germany for tube plate processing. This significantly improves the accuracy of hole drilling and the smoothness of hole surfaces, creating favorable conditions for subsequent expansion joint processes. You can know more about the advantage of this processing in our fire tube boiler catalogue.
• Inability to Scale Up
  Flat tube plates have limited structural strength, making them unsuitable for high-pressure applications and large-scale boilers, typically not exceeding 20 steam tons.
  Whether it is a 6-ton or a 20-ton boiler, ZOZEN’s tube plates are punched out of a single piece of steel plate without any splicing process. This not only reduces manufacturing costs but also eliminates the need to consider avoiding weld seams during hole design, resulting in higher-quality boilers.
