WNS Integral Gas or Oil Fire Tube Condensing Steam Boilers

External and separate energy saving devices and anti-corrosive condenser on the Devotion Condensing Steam Boilers can recover heats in the exhausted flue. The after-flue temperature is lowered under 70℃. Latent heat released when smoke condensates is maximally utilized, in the meanwhile, unique frequency scaling continuous water feed and proportional combustions can largely increase heat efficiency, i.e, save the fuels. In the re-utilization of energy, harmful emission can also be reduced and thus lessen impact on the environment.

Advantages

• Two Stage Energy Saving.  Absorb heat of exhaust flue by taking advantage of economizer and condensate vapor through finned-tube condenser to recover 5% of the afterheat and decrease exhaust flue temperature to 70℃.
• All Wetback Three Pass Structure  Heat is thorough absorbed when flue goes through chamber, fire tubes, economizer. The boiler features compact configuration, packaged for delivery, fast and easy installation.
• Low Nox Combustion   Big hearth specially designed to achieve super low NOx emission, together with full premix combustion technology (FPB technology ) and flue gas recirculation(FGR) technology, lower the emission of NOx below 30mg/m³.
• Corrugated furnace plus threaded fire tubes.  Increase heating surface of the hearth, and avoid damages to the hearth resulted from Expansion and Contraction, and reduce flue resistance and improve heat efficiency assisted by threaded fire tubes.
