Introduction
WNS Series Gas Oil Fire Tube Boiler
WNS fire tube boiler is a horizontal, internal combustion, three-pass boiler designed to provide a reliable supply of steam for industrial applications. It uses a wet-back with hot flue gases passing through the furnace and fire tubes to transfer heat to the surrounding water.
It is widely used in food processing, textile manufacturing, pharmaceutical production, paper mills, chemical plants, and other industries.
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BV, ensuring high quality and compliance with international standards.
Boiler Features & Avantages
Wet-Back, Corrugated furnace, Three-Pass Design: Optimized heat transfer structure for efficient heat utilization and reliable steam production.
High Efficiency: Reduces fuel consumption and helps lower operating costs.
Fully Automatic Operation: Automatic combustion control for convenient operation and stable performance.
Low Emissions: Optimized combustion helps reduce pollutant emissions.
Portable Skid-Mounted Design: Integrated equipment simplifies transportation, installation, and commissioning.
Mobile Boiler Option: Flexible mobile configurations allow convenient relocation to different work sites.
Boiler System Configuration
WNS boiler can operate on fuels such as natural gas, diesel, and light fuel oil, depending on the burner configuration. Fuel selection can be based on local availability, operating costs, and emission requirements.
The boiler system can be configured with auxiliary equipment such as a feedwater pump, economizer, water treatment system, steam separator, blowdown system, and chimney according to project requirements.
