Frequently Asked Questions
The wet-back design reduces the need for refractory materials in the rear chamber, lowering maintenance costs and improving overall heat transfer efficiency by keeping the heating surfaces submerged in water.
Corrugated tubes create turbulent flow in the flue gas, which significantly increases the heat transfer coefficient compared to smooth tubes, while also allowing for better thermal expansion without stressing the boiler structure.
Yes, the WNS series is designed for versatility. Depending on the burner configuration, it can be operated as a gas-fired or diesel-fired boiler, providing operational flexibility based on local fuel pricing.
We employ a low-level combustion chamber design which creates a larger water level safety buffer, reducing the risk of accidents caused by sudden water loss or sensor failure.
The economizer recovers waste heat from the flue gases to preheat the incoming feed water, which significantly lowers fuel consumption and increases the overall boiler efficiency.
With proper water treatment and regular maintenance of the international-brand burners, these boilers are engineered for long-term industrial durability, typically lasting several decades.
