Analyze from 5 aspects for you, what are the root causes of the insufficient suction of the fireplace chimney?

The problem of fireplace chimney pumping is more complex, there are many key constraints can be said to affect the size of the fireplace chimney pumping, and once the fireplace chimney pumping is insufficient, the worst result is that the fireplace is affected to the point of normal operation. Therefore, in order to avoid this phenomenon, the correct and strict installation of the fireplace chimney is particularly important, and the purpose of doing a good job of the source is to ensure the normal operation of the fireplace chimney. Next, I will analyze for you from 5 aspects, what are the root causes of the insufficient suction of the fireplace chimney?

1, fireplace chimney caliber is not suitable

From the perspective of 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 chimney caliber of the fireplace, it is completely incorrect, because a set of suitable fireplace chimney is particularly important from the use level, for the modern true fire fireplace lift will be larger, it will lock more heat that may escape to the outside through the pipeline, making the thermal efficiency of the modern true fire fireplace higher. When the flow of heat in the chimney is gradually reduced, the large diameter fireplace chimney will not have enough ascending thermals to gather and form, causing the problem of insufficient pumping force. So when you buy a fireplace chimney, be sure to choose a suitable diameter for installation.

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 to form a good suction force in the chimney, the premise is to ensure that the smoke in the chimney rises as straight as possible. Therefore, when installing the chimney, try to keep the chimney straight up and straight down, and every bend of the chimney will cause resistance to the smoke rising. If the chimney installation has lateral displacement, it is also necessary to comply with the chimney installation standards, the vertical height of more than 5 meters, and the horizontal displacement does not exceed 20% of the vertical height.

3, fireplace chimney exhaust smoke, exhaust gas temperature is too low

If the chimney pumping force is explained from the physical point of view, the principle is nothing more than a force generated by the pressure difference between the temperature outside the space and the temperature at the chimney outlet. The greater the temperature difference, the greater the force, that is, the pulling force, and the relationship between the two is proportional. Therefore, under normal circumstances, professional and experienced installation workers will recommend that you use a double-layer smoke pipe with good insulation performance outdoors, and use a single-layer smoke pipe with good economic efficiency indoors, in order to achieve the highest cost performance and reduce or eliminate the problem of insufficient suction of the fireplace chimney because of the smoke discharged by the fireplace chimney and the low exhaust gas temperature.

4. Poor air circulation in the space

Another important factor that causes a fireplace chimney to draw less or less is the formation of negative air pressure in the room. In recent years, due to the complete improvement of the decoration process, on the one hand, the villa decoration is becoming more and more precise and rigorous, but also cause the air supplement in the burning state of the fireplace under normal circumstances is imperfect, forming an illusion that the suction force in the chimney of the fireplace is decreased, which is unavoidable if studied from the architectural point of view alone. Therefore, we can only do when the fireplace is in a burning working state, as little as possible to open the home with the exhaust fan equipment, to avoid the formation of an indoor negative pressure, if this can not be met, it is recommended to open the window, natural ventilation, to ensure the smooth flow of air in the space, is to eliminate the fireplace chimney pumping insufficient a key factor.

5. Other uncontrollable and irresistible reasons



In fact, it is very frustrating to say that in addition to the attention of the fireplace chimney in the correct installation and standard use, there are some uncontrollable and irresistible other reasons that will affect the fireplace chimney pumping force, resulting in its lack of power, such reasons mainly include but not limited to the design structure of the house roof, the height of the trees around the house, the wind speed and direction of the area where the house is located. When you encounter this kind of problem, the best solution is to contact a reliable fireplace dealer for you to solve.
