1. Energy saving: three though can fully use the fuel, make the hot water is quick-out; and the outside covered heat-insulated material also can effectively stop the heat loss. The thermal efficiency can reach 90%-92%.
Advantages:
1.Wet-back type boiler, reduce the heat losses, increase heat absorbing area.
2.Big furnace design, increase the drum diameter and heat transfer area.
3.Reduce the noxious gas production,improve heat efficiency.
4.Strong burning fuel adaptability, such as heavy oil, light oil and so on.
5.Heat transfer strengthen technologies application, smoke velocity design optimization
6.Overtemperature,overpressure,water lackage,flameout and the other protect functions
The wns hot water boilers have the characteristics of reasonable structure, safely running, high efficiency, energy saving and conveniently operation. WNS series automatic oil-fired boiler ,and wns gas-fired boilers were adopted advanced international three-pass and wet back structure.
