WNS Series Gas Hot Water Boilers
  1. Full-waveform furnace structure avoids cracking caused by stress concentration, extending boiler's service life.
  2. Unique "welding & expansion" process prevents subcooled boiling at the tube and plate welds, ensuring a safe, reliable and stable boiler operation.
  3. Staggered tube bundles facilitate steam drums carrying and evenly distribute heat to the tube walls.
  4. Rational set of flue gas temperature at three-pass outlet prevents low-temperature corrosion.
  5. Multifunctional explosion-proof doors ensure safe use and easy maintenance.
  6. Independent design of fixed movable supports allows for flexible thermal expansion and contraction.
Performance Feature -Energy Saving
  1. Increased heating surface of the tail finned tubes provides higher heat exchange efficiency
  2. Smoke tube adopts special threaded tube to reduce smoke flow resistance and enhance the heat transfer effect.
  3. Economizer (condenser) adopts patented technology with independent intellectual property rights, taking into account both heat transfer efficiency and operation resistance;
  4. Multi-stage "stepped" sealing provides excellent thermal insulation and sealing performance.
  5. Frameless outer-clad structure & entire coating with heat-resistant paint minimize the heat losses.
Performance Feature -Emission Reduction
  1. Large combustion chamber design enables fuel to burn more fully and thoroughly at a relatively low furnace volume heat load, and nitrogen oxides are less than 30mg/Nm³.
