WNS Biomass Steam Boiler (Horizontal Fire-Tube Type)
Biomass boiler for industrial steam generation and energy cost reduction.
Description：
WNS vs DZL/SZL Boiler Types
WNS and DZL/SZL boilers use different heat exchange structures, which affect installation, efficiency, and application.
WNS Boiler (Fire-Tube Type)
In WNS boilers, hot gases flow inside tubes while water surrounds the tubes. This compact design allows faster steam generation, easier installation, and stable operation, making it suitable for small to medium industrial applications.
DZL / SZL Boiler (Water-Tube Type)
In DZL/SZL boilers, water flows inside tubes while hot gases pass around them. This design supports higher capacity and heat transfer efficiency, but requires more space and a more complex system.
Feature
