This technology can recover the residual heat in the flue gas, thus improving the thermal efficiency of the wall-hung boiler. Specifically, the working principle of condensing wall-hung boiler is to recover the condensation heat of water vapor in high-temperature flue gas through condensation technology, which can not only reduce the waste of energy, but also further improve the thermal efficiency of wall-hung boiler.
Compared with traditional wall-hung boilers, the main advantages of condensing wall-hung boilers include higher thermal efficiency and lower energy consumption. The thermal efficiency of partial condensation wall-hung boiler can even reach 109%, which is about 25% higher than that of ordinary wall-hung boiler. In addition, the combustion chamber of condensing wall-hung boiler is usually made of stainless steel or silicon-aluminum alloy, which has good acid resistance and corrosion resistance, and there is no temperature limit on the return water temperature, so the service life is longer, up to 20 years.
Characteristics of condensing wall-hung boiler
1, high efficiency and energy saving: condensation technology can use the latent heat contained in water vapor in gas flue gas to reduce the temperature of flue gas to below 100℃, recover water vapor, and finally improve thermal efficiency. The thermal efficiency of condensing wall-hung boiler can reach more than 100%, which is more energy-saving and emission-reducing than traditional boilers.
2. Environmental protection: the condensing wall-hung boiler can meet the emission standard of zero pollution and is environmentally friendly.
3. High safety: the condensing wall-hung boiler adopts full automatic control and multiple protections, making it safer and more reliable to use.
4. Long service life and simple maintenance: The components of the condensing wall-hung boiler are made of high-quality materials, which have the advantages of corrosion resistance, erosion resistance and impact resistance, and the service life is longer and more stable. At the same time, the condensation wall-hung boiler adopts a brand-new mixed heat combustion in design, and the combustion mode is fully premixed proportion adjustment, and the pipeline can be designed in large size. Even if it is used for a long time, there is no need to worry about scaling and blocking the pipeline.
