Product Description

DuAo D6 series boilers adopt full premixed plane combustion technology. Through precise adjustment and control, they ensure that gas and air are fully mixed to achieve full combustion and high thermal efficiency. The furnace required for flat combustion is shorter, which can effectively reduce the boiler volume. The temperature gradient in the furnace is more uniform, the heating surface is uniform, and the heat transfer effect is superior. Duiao D6 series boilers have exhaust smoke as low as 20℃, which is comparable to normal outdoor temperature. It not only reduces the emission of nitrogen oxides such as CO2 and S02, but also reduces the pollution to the air environment. It also solves the problem of white smoke from gas boilers, which saves energy. And environmentally friendly.

Ultraten Technology - Wing Tube

DUAO 6 series boilers adopt fully premixed horizontal combustion technology. Through precise regulation and control, gas and air are fully mixed, combustion is complete, and thermal efficiency is high. The furnace required for flat combustion is shorter, which can effectively reduce the boiler volume. The temperature gradient in the furnace is more uniform, the heating surface is uniform, and the heat transfer effect is superior。

Ultra-high speed cooling tube technology

Combined with the heat transfer and condensation functions of the wing tubes, under unit operating conditions, the special tearing groove design of the wing tubes allows it to have a heat exchange area 5 times that of ordinary light tubes, and can effectively eliminate the condensation film on it. The heat transfer material is also made of silicon-aluminum alloy, which has high heat exchange efficiency and corrosion resistance.

condenser

DUAO 6 series boilers adopt volumetric wing tube condensers, which have the characteristics of small flow resistance and large flow rate. The wing tube condenser extracts the sensible heat and part of the latent heat of the flue gas at the end to achieve primary condensation of the flue gas. After primary condensation, the flue gas still has some latent heat available for use. We creatively added a deep condensation module to achieve deeper secondary condensation of flue gas. The flue gas precipitates a large amount of condensed water in the deep condensation module, and the heat is continuously recovered. to the furnace body to increase the boiler inlet water temperature and reduce gas consumption.

deep condensation

DUAO D6 series boilers use a dual combination of condenser and low-temperature cooler to deeply condense the flue gas and reduce the exhaust gas temperature to 20°C, which is equivalent to the normal outdoor temperature. Not only is the final recovery of the latent heat of the flue gas achieved and the thermal efficiency of the boiler improved, but the treated condensate can still be used to supplement boiler water, reducing boiler water consumption. As the temperature of the exhaust flue gas decreases, harmful components in the flue gas dissolve in the condensed water, directly or indirectly reducing the emission of nitrogen oxides such as CO2 and SO2, and reducing the impact on the air environment.
