Optimized Three-Pass Design:

WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.

Innovation in Three-Pass Design:

ZOZEN Boiler‘s three pass boiler is a highly efficient boiler known for its thermal efficiency of over 98%. It incorporates key features such as a corrugated furnace, threaded smoke tubes, and a condenser.

The corrugated furnace design enhances the boiler’s strength and provides a larger surface area for heat transfer, resulting in improved combustion efficiency. The threaded smoke tubes increase heat exchange efficiency by prolonging the contact time between the flue gas and the water, maximizing heat absorption. Additionally, the condenser plays a crucial role in recovering heat from the flue gas by condensing water vapor, further enhancing the overall energy efficiency of the boiler.

Automated Operations and Safety:

The three pass boiler offers seamless automation and remote control capabilities, thanks to advanced control systems. This enables unmanned operation, minimizing human intervention and enhancing convenience. With remote monitoring and control, real-time adjustments can be made, ensuring optimal performance and proactive maintenance. Leveraging IoT technology and expert management, the boiler provides peace of mind while maximizing efficiency.

In addition to automation, the three pass boiler prioritizes maintenance convenience and safety. The comprehensive control system allows for easy monitoring, diagnostics, and preventive maintenance, reducing downtime. Safety is reinforced by advanced burner technology and a low-NOx combustion design, limiting emissions to ≤30mg/Nm³. These features not only protect the environment but also comply with stringent emission regulations, ensuring a reliable and environmentally friendly operation.

The WNS series three pass boiler from ZOZEN Boiler is a game-changer in the heating industry. Choose ZOZEN Boiler to elevate your business’s heating capabilities and achieve sustainable success.
