Yongxing Condensing Steam Boiler Reliable Quality

Yongxing Boiler Group is one of the top 10 condensing boiler manufacturers in China. Our condensing steam boiler mainly refers to an industrial condensing boiler.

Product Description:

With years of experience making boilers, Yongxing has made WNS type integrated condensing boilers that are environmentally friendly and save energy.

Because this boiler has a condenser on the surface, it’s different from the WNS type oil and gas boiler. The addition of a condenser lowers the boiler’s exhaust temperature to between 60 and 80°C. It also takes some of the heat energy from the flue gas, which makes the boiler more efficient.

At the same time, the process of reusing energy cuts down on the number of harmful gases and pollutants that are released into the air. Because this boiler is both energy-efficient and environmentally friendly, it is used a lot in the food, clothing and textile, petrochemical, and equipment manufacturing industries, as well as many others.

These parts make up a WNS type integrated condensing boiler. They include the boiler, the burner, and the instrument. The condenser and water tank are also part of the boiler.

Once you have different fuels, we will offer you more models of condensing steam boiler.

In traditional gas oil fired steam boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, and the water vapor in the flue gas is still in a state of superheating, so it is impossible to condense into liquid water and release the latent heat of vaporization. Therefore, the thermal efficiency of traditional boilers can only reach 87%-91%.

But Yongxing condensing Steam Boiler reduces the exhaust gas temperature to 50-70 ℃, fully recovers your sensible heat in the flue gas and the latent condensation heat of water vapor. Thus, we could finally realize your high-efficiency condensing boiler with 99.8%.
