WNS Series Gas/Oil Fired Condensing Boilers Introduction

WNS series gas/oil condensing boilers are fire tube, three-pass, wet-back boilers that stands out for their excellent condensing technology. The application of condensing technology is the core advantage of the WNS series gas/oil fired condensing boiler. By utilizing the heat in the flue gas and fully recovering the thermal energy in the water vapor, it achieves a substantial improvement in thermal efficiency. Compared to traditional boilers, condensing boilers greatly save energy consumption. The condensing technology also lowers the flue gas emission temperature, reducing environmental pollution and meeting the modern society’s requirements for environmental protection and sustainable development.

WNS Series Gas/Oil Fired Condensing Boilers Advantage

Complete Combustion: The large furnace design provides a larger combustion space, ensuring a more thorough and stable combustion process. The fuel has more time and space within the furnace to fully mix and burn with the air.

Thermal Efficiency ≥98%: The large furnace design incorporates corrugated furnace walls and threaded smoke tubes to enhance heat transfer efficiency. The economizer and condenser utilize finned tubes to increase the heating surface area, improving heat transfer efficiency and reducing flue gas temperature.

Easy Maintenance: Advanced control systems enable unmanned operation.

Eco-Efficient: The use of low-NOx burners and advanced low-NOx combustion technology ensures NOx emissions ≤30mg/Nm³.
