Description：

Our gas-fired boiler is a horizontal internal combustion three-pass full wet-back boiler. It features a fully corrugated furnace, increasing heat transfer area and enhancing stability. Constructed using full flange butt welding, it minimizes thermal stress. The 'expand first, then weld' technique eliminates corrosion issues and extends the boiler's lifespan. The smoke tubes have helical internal ribs, improving heat exchange efficiency. With high thermal efficiency and low fuel consumption, the WNS series offers automation, stable outputs, and easy maintenance. Installation is simple and time-efficient.
