The cause of the fireplace chimney extraction problem

1. The diameter of the fireplace chimney is not suitable

Based on the understanding and analysis of some distorted purchasing behaviors in traditional Chinese concepts, the vast majority of consumers believe that bigger is better! If this applies to the diameter of the fireplace chimney, it is completely incorrect, because a suitable set of fireplace chimneys is particularly important in terms of use. For modern real fire fireplaces, the upgrade will be greater and more locks will be locked The thermal energy that may escape to the outside through the pipes makes the thermal efficiency of modern real fire fireplaces more efficient. When the heat energy circulation in the chimney is gradually reduced, the large-diameter fireplace chimney will not have enough rising hot air to form, resulting in the problem of insufficient drawing power of the fireplace chimney. So when you buy a fireplace chimney, be sure to choose the one with a suitable diameter for installation and use.

2. There are too many meaningless corners in the horizontal direction of the fireplace chimney, and the vertical height does not exceed about 5 meters

In order for the chimney to form a good suction, the premise is to ensure that the flue gas in the chimney rises as straight as possible. Therefore, when installing the chimney, try to keep the chimney straight up and down. Every elbow of the chimney will have resistance to the rise of the flue gas. If the chimney is installed with lateral displacement, it is also necessary to comply with the chimney installation standards. The vertical height is more than 5 meters, and the lateral displacement does not exceed 20% of the vertical height.

3. The temperature of flue gas and exhaust gas discharged from the fireplace chimney is too low

From the perspective of physics, the principle of chimney pulling force is nothing more than a force generated by the pressure difference between the temperature outside the space and the temperature of the chimney outlet. The greater the temperature difference, the greater the acting force, that is, the greater the pulling force, and the two are proportional. Therefore, in general, professional and experienced installers will recommend that you use double-layer smoke pipes with better thermal insulation performance outdoors and single-layer smoke pipes with better economic benefits indoors, in order to achieve the highest cost performance while reducing or eliminating. Because the flue gas and exhaust gas temperature from the fireplace chimney is too low, the fireplace chimney is insufficiently drawn.

4. Poor air circulation in the space

Another important factor that causes the drawdown or insufficient of the fireplace chimney is the formation of negative indoor air pressure. In recent years, due to the complete improvement of the decoration process, on the one hand, the decoration of villas has become more and more precise and strict, and at the same time, it will also cause the air supply in the burning state of the fireplace to be incomplete under normal circumstances, resulting in a decrease in the drawing force in the chimney of the fireplace. This aspect is unavoidable if we study from the perspective of architecture, so we can only do it when the fireplace is in the burning state, try to turn on the equipment with the exhaust fan in the home as little as possible to avoid the formation of an indoor negative air pressure , If this can not be satisfied, it is recommended to open the windows for natural ventilation to ensure smooth air circulation in the space, which is a key factor to eliminate the insufficient suction power of the fireplace chimney.

5. Other uncontrollable and irresistible reasons

In fact, it is very frustrating that, apart from the precautions for the correct installation and standardized use of the fireplace chimney, there are some uncontrollable and irresistible other reasons that will affect the drawing force of the fireplace chimney, resulting in its lack of power. The reasons mainly include but are not limited to the roof design structure of the house, the number of trees around the house, the wind speed and direction of the area where the house is located, etc. When you encounter such a problem, the best solution is to contact a reliable fireplace dealer. The dealer will solve it for you.
