Steam Boiler for Bitumen Heat in Mongolia

• Project: Steam Boiler for Bitumen Heat in Mongolia
• Industry: Construction
• Boiler Type: WNS Series Horizontal Type Fire Tube Steam Boiler
• Boiler Model and Quantity: 2 sets of WNS2-1.0-YQ

On Mar 6^th of 2019, one customer from Mongolia placed an order of 2 complete boiler systems to us, which includes steam boiler WNS2-1.0-YQ, heavy oil burner Unigas(Italy brand), water softener, pump, etc. 
This boiler is fueled by heavy oil to produce steam with capacity 2tons per hour @ 10bars(1MPa) to heat bitumen in barrel to 150℃ and keep around 100℃, so that the bitumen can be fluid and easy to mix aggregates for road construction.

We got the receipt of the deposit USD22,004 on Mar 11 and arranged the production immediately. 15days later, we delivered the goods by truck to Ulaanbaatar via Erenhot.

Characteristics of WNS series horizontal type fire tube steam boiler:

• Wet back three-pass fire tube boiler with reversal burning chamber;
• Laddering heat recovery can greatly increase boiler efficiency;
• The double-layer sealing structure of front smoke box door and panel adopts  aluminium silicate board as insulation material, with high thermal insulation and sealing effect;
• Detachable spring explosion-proof door ensures safety, also can be used as inspection hole;
• Continuous variable frequency water supply, ensures pump and burner run coordinately and stably.
• Waste heat recovery in flue gas lowers exhaust temperature to 95℃, and improves efficiency to 98 .5 %;
• Discharge of NO_X , CO_X , SO_X and other harmful substances has been greatly reduced;
• Compared with traditional four water level alarms , there is a fifth water level  detection, further strengthening safety automatically;
• The range of steam pressure can be set by touch screen , achieving automatic and accurate control;
• Big water volume with strong adaptability to heat load.
