Introduction

WNS series oil/gas fired boiler adopts horizontal three-pass wet-back structure,large corrugated furnace and patented thread pipe technology,equipped with international first-level brand burners and valve groups,and independently developed high-matching PLC control system to realize muitiple linkages.The lock protection function protects the equipment running safely.

Feature 

Advanced three pass wet back design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.

Advanced manufacturing equipment endows Safe and reliable property:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.

 Large boiler proper heating area:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.

High efficiency 98%:with threaded pipe and high effective insulation materials and econoizer, increasing the heat transfer and improve boiler thermal efficiency.

PLC intelligent controller:boiler control system suitable for high temperature, high humidity environment of long-term operation.

High standard: strictly in accordance with Chinese national norms and standards of production, all boiler pressure parts are of high quality steel.
