WNS series is a classical shell type steam boiler, with classical design: firetube+ wetback+ 3pass. Its average thermal efficiency >95%, design working life span more than 15 years. Equipped with well-known auxiliary parts, such as BALTUR/RIELLO- Burner, DANFOSS- Pressure Controler, SIEMENS- PLC operation system, LEO- Multistage Pump, etc. to ensure the boiler's steady performance. The entire system warranty period: 2 Years.
Free-Installation
Before the shipment, complete boiler system is well skid-mounted on the basement, also we have done the pipe(valves) connection and wire connection. After receiving the boiler, no need installation/ assembly. Just join the boiler to water/ gas/ electricity. Comparing with other traditional boilers in the market, our boiler does save lots of cost/ energy/ time in installation. The additional, the entire boiler system is portable.
Structural characteristics
1. Adopt horizontal full wet back structure, compact overall layout, beautiful and generous, high thermal efficiency.
2. Adopt micro-positive pressure operation, effectively improve the combustion intensity of the furnace, make the volume of the same capacity boiler smaller, at the same time eliminate the boiler furnace, flue air leakage, improve the thermal efficiency of the boiler.
3. External integrated finned tube economizer, external independent condenser, compact structure, easy maintenance, the use of the current more popular condensation technology, reduce the smoke exhaust temperature, improve thermal efficiency.
4. Adopt advanced EDA design technology, calculate furnace structure and size in detail, effectively control flue gas velocity and resistance, reasonably make full use of flame and flue gas heat exchange, improve boiler thermal efficiency.
5. The corrugated furnace structure not only increases the heating area but also increases the disturbance of the flue gas, and the threaded flue gas technology increases the convection heating surface.
6. Use frequency conversion water supply and control technology to ensure the condensation rate of water vapor in the flue gas.
7. The condenser adopts special steel with "low dew point corrosion resistance of sulfuric acid", which greatly improves its service life.
8. Adopting reasonable structural design and excellent fire-resistant and thermal insulation materials, the external temperature of the furnace body is greatly reduced to make the external temperature below 50 degrees (higher than the national standard), reducing heat loss and improving the thermal efficiency of the boiler.
9. Adopt a new design to reduce the emission of harmful substances during fuel combustion and meet the national environmental protection standards, especially the emission of nitrogen oxides, and meet the national low nitrogen emission standards.
10. Imported burners from many international famous brands are adopted to adapt to various application scenarios to ensure quality and safety.
