The exhaust gas problem of wall-hung boiler mainly stems from incomplete combustion, heat exchanger problem, flue blockage and other reasons. In view of these problems, the following measures can be taken to solve the problem of wall-hung boiler exhaust gas:
Ensure gas quality: The use of high-quality gas can reduce the exhaust gas generation of wall-hung boilers. If natural gas is used, it should be ensured that it is stable and of good quality.
Check the burner: The burner of the wall-hung boiler is a key factor affecting the exhaust emissions. If there is a problem with the burner, such as insufficient gas pressure, abnormal flames, etc., it should be adjusted and repaired in time. You can ask a professional to inspect and clean the burner to ensure that it is working properly.
Cleaning the heat exchanger: The heat exchanger is the core component of the wall-hung boiler, and if it is corroded or blocked, it will affect its heat dissipation effect, resulting in an increase in exhaust emissions. Regular cleaning and maintenance of the heat exchanger can keep it in good working order and reduce exhaust emissions.
Clean the flue: The flue of the wall-hung boiler is easy to accumulate dust and debris, resulting in obstruction of exhaust emissions. Regularly cleaning the wall-hung boiler flue to ensure that it is unobstructed can help reduce exhaust emissions.
Increase ventilation: Wall-hung boilers need the right amount of air to burn properly. If the indoor air circulation is not smooth, it will lead to insufficient air absorption by the wall-hung boiler, which will affect the combustion effect and increase the exhaust gas emission. Therefore, the amount of indoor ventilation can be increased, such as opening windows for ventilation, using exhaust fans, etc., to ensure smooth air circulation.
Update the equipment: If the wall-hung boiler has been used for a long time or the technology is outdated, there may be a problem of high exhaust emissions. In this case, you can consider updating your equipment and choosing a more efficient and environmentally friendly wall-hung boiler to replace the old one.
In addition, for the problem of exhaust gas treatment, the following methods can be adopted:
Flue gas purification method: Install flue gas purification equipment, such as filters, adsorbents, chemical absorbers, etc., to remove harmful substances. This method can effectively reduce the emission of pollutants from combustion.
Central heating method: multiple wall-hung boilers are connected through pipes to form an integral heating system. In this way, the exhaust gas can be treated and utilized in a centralized manner, for example by improving the thermal efficiency of the wall-hung boiler through waste heat**.
Activated carbon adsorption method: the exhaust gas is adsorbed on the surface of the activated carbon through the action of activated carbon. Activated carbon has the advantages of strong adsorption capacity, low cost and easy use. However, it should be noted that activated carbon needs to be regenerated after adsorption, otherwise the adsorption efficiency will be reduced.
In short, in view of the exhaust gas problem of wall-hung boiler, corresponding solutions should be taken according to the specific situation, which not only ensures the warmth and comfort of the family, but also protects the environment and human health. At the same time, regular maintenance and inspection of wall-hung boilers are also important measures to prevent exhaust gas problems.
