Adjusting the stove's shaft is key to optimizing the combustion process, energy efficiency and the safety of homeowners.
Introduction
The damper, which is a flap that regulates the flow of air in the chimney, allows you to control the amount of oxygen supplied to the furnace and affects the intensity of combustion. Read the text below to learn how to properly set the damper on your stove!
The shaft function in the stove - what is it?
The stove's shaft is a mechanism that allows you to control the chimney draft. By adjusting the shaft, you can increase or decrease the amount of air escaping through the chimney, which directly affects the rate of combustion. Proper adjustment of the shaft is therefore important both for combustion efficiency and for safety, by preventing smoke and fumes from backing up into the room.
The shaft in the stove performs several important functions that are essential for the efficient and safe operation of the heating system. Among the most important are:
-
Regulation of the chimney draught.
-
Control of the combustion process. The shaft allows for more precise control of the combustion process. Proper setting of the shaft helps achieve optimal combustion, which is important both in terms of energy efficiency and minimizing harmful emissions.
-
Improving energy efficiency. Reducing the amount of air escaping through the chimney allows the stove to stay warm longer, resulting in reduced fuel consumption and lower heating costs.
-
Prevention of smoke backflow into the room. Proper positioning of the shaft helps maintain proper draft in the chimney, which promotes the proper discharge of smoke and fumes to the outside.
How to properly adjust the furnace damper?
When you start a fire in the stove, the damper should be fully open. This allows intensive airflow, which is essential for starting a fire. An open damper increases the chimney draft, which makes it easier to vent smoke and flue gases to the outside.
On the other hand, once the fire is lit, you can begin to gradually close the chimney shaft to reduce airflow. This translates into slower and more controlled combustion, which in turn increases energy efficiency as heat is released over a longer period of time.
When burning, the setting of the shaft depends on the type of fuel, the power of the firebox and the preferred temperature. Typically, the shaft is partially closed, which allows the fire to remain stable and ensures optimal combustion levels.
Is the damper open or closed?
-
Open shaft - is recommended during kindling and in situations when you want to quickly increase the temperature in the stove. Full opening of the shaft is also necessary when you need to quickly release accumulated smoke and fumes, for example, when opening the stove door.
-
Closed shaft - closing the shaft is advantageous when you want to reduce the intensity of burning and at the same time increase the efficiency of combustion. A closed shaft slows the escape of warm air through the chimney, so the heat is better used for space heating. However, complete closure of the shaft can lead to incomplete combustion and accumulation of harmful gases, so never close the shaft completely while burning.
Thoughtful management of the stove's shaft is the foundation of efficient and safe home heating. Keep in mind that each stove may operate slightly differently, so it is a good idea to adapt these tips to your own experience and the specifications of the equipment you are using.
