WNS Gas Oil Fired Steam Boiler

WNS Gas Oil Fired Steam Boiler

Overview

The WNS oil/gas fired steam boiler is three-return fired tube steam boiler with wet back structure. The high temperature flue gas will be injected into the atmosphere after convection heat transfer through the reversal chamber into the first flue tube bundle and then from the front smoke box with turning 180℃ into the second flue tube bundle.

 

Advantage

1, Sitong patented technology: 100% completely butt welding, minimum stress and more reliable quality.
2, Large diameter corrugated furnace: Combustion chamber is composed by large diameter full corrugation furnace, big combustion space.
3, High steam quality: Large steam space volume and enough height of the net distance between steam water interface and steam outlet.
4, Advanced automatic control: Boiler controller use Siemens/Delixi electrical element, reliable property.
5, Multi-function safety explosion proof equipment: Boiler rear panel is equipped with explosion proof equipment which connected with furnace.
