WNS Industrial Oil Fired Steam Boiler Packaged Unit

High-Atomization Liquid Fuel Steam for Remote & Off-Grid Plants

Specifically engineered for industrial installations without access to natural gas pipeline networks, the EPCB WNS oil fired steam boiler features an enlarged wave-type combustion chamber and high-atomization European pressure-modulating burners (Baltur/Riello). Whether firing standard light diesel, heavy fuel oil (HFO), or marine fuel, it guarantees complete droplet burnout, minimal carbon buildup, and rapid thermal response.

Broad Fuel Capability: Efficiently handles 0# diesel, light oil, kerosene, and preheated heavy fuel oil (HFO).

Heavy Fuel Preheating Skid: Equipped with dual electric & steam oil preheaters for smooth heavy oil viscosity regulation.

100% X-Ray Radiographic Check: Full non-destructive testing of all pressure-retaining seam welds before shipping.

Fail-Safe Multi-Stage Protection: Automatic flameout photocell shutoff, low water level cutoff, and overpressure interlocks.
