Frequently Asked Questions
A wet-back design reduces the need for refractory materials in the rear chamber, lowering maintenance costs and improving heat transfer efficiency compared to dry-back designs.
The finned tube economizer recovers waste heat from the flue gas to preheat the feed water, significantly reducing the amount of fuel required to reach boiling point.
Yes, the WNS series is designed to be compatible with either gas or diesel firing systems depending on the burner configuration selected during procurement.
Corrugated tubes increase the heat transfer surface area and create turbulence in the gas flow, which enhances efficiency and allows the metal to expand and contract without cracking.
Regular nozzle cleaning, flame sensor inspection, and air-fuel ratio tuning are recommended to maintain the 92%+ efficiency rating.
Capacity selection depends on your peak steam demand. Our range from 1 t/h (WNS1) to 20 t/h (WNS20) allows for precise scaling based on your production volume.
