WNS ultra-low NOx gas-fired boiler

The WNS-type ultra-low nitrogen gas-fired boiler is a shell-type three-pass wet-back gas-fired boiler produced with advanced technology. It consists of the boiler body, connecting flue, deaeration pump, deaerator, burner, steam-water system, instruments, and economizer.

Key Feature: Low nitrogen emission (below 30mg/m³), meeting strict environmental requirements while maintaining a compact and reliable structure.

Functions and Advantages

1. High-Efficiency Heat Energy Conversion: Adopting a three-pass structure combined with threaded smoke tubes and corrugated furnace liners, the thermal efficiency can reach over 92%.

2. Ultra-Low Nitrogen Oxide Emission: Flue gas recirculation (FGR) and staged combustion control NOx below 30mg/m³.

3. Full-Automatic Intelligent Control: Equipped with PLC intelligent control system, supporting one-key start-stop and automatic adjustment.

4. Multiple Safety Protections: Overpressure, overtemperature, and water shortage protection ensure safe industrial operation.

Industrial Applications

This boiler serves diverse industries including Food Processing, Textile Printing, Chemical Industry, Pharmaceutical, Central Heating in Industrial Parks, and Building Heating for residential or commercial complexes.
