To keep your home comfortable and cut down on energy expenses, make sure your insulation and heating system are operating efficiently. The correct supply of secondary air to the furnace is one of the many components that make up a well-performing heating system. We’ll go into the significance of secondary air supply and how it affects your heating system’s overall performance in this post.
Let’s first clarify what secondary air supply means. Primary air is the air that mixes with the fuel during combustion in a furnace or other combustion appliance. Secondary air, however, has a distinct function. After the primary combustion has begun, it is the additional air supply that is added to the combustion chamber. In order to effectively complete the combustion process and lower harmful emissions, this secondary air is essential.
A primary advantage of an appropriate secondary air supply is enhanced combustion efficiency. Insufficient air supply can cause incomplete combustion, which can result in fuel waste and higher emissions of pollutants like particulate matter and carbon monoxide. More heat can be produced from the same amount of fuel by optimizing the combustion process and making sure there is a sufficient supply of secondary air.
Furthermore, a sufficient secondary air supply encourages cleaner burning and lessens soot and creosote accumulation in the chimney and furnace. In addition to lowering your heating system’s efficiency, soot and creosote present a fire risk. In the end, you can prolong the life of your furnace and chimney by maintaining a safer and cleaner combustion environment with adequate secondary air.
Additionally, improved control over combustion temperature and flame stability are facilitated by the secondary air supply. The proper quantity of secondary air aids in controlling the temperature inside the combustion chamber, preventing the furnace from overheating or not heating the furnace sufficiently. For heating to operate consistently and dependably during the winter, temperature and flame stability control are crucial.
To sum up, secondary air supply is essential to maximizing the efficiency of your furnace and guaranteeing effective home heating. Understanding secondary air’s significance and taking the required actions to supply enough of it will help you improve combustion efficiency, lower emissions, and extend the life of your heating system. Watch this space for our next articles, where we’ll discuss doable strategies to enhance secondary air supply in various furnace types.
The argument over secondary air supply vs. proper furnace breathing is vital to the search for a safe and effective home heating system. While proper furnace breathing ensures that the combustion process operates optimally, preventing issues like backdraft and incomplete combustion, secondary air supply involves introducing additional air into the combustion process to enhance efficiency and reduce emissions. Both strategies seek to maximize heat output while lowering risks to public safety and the environment. For homeowners looking to maximize the performance and sustainability of their heating systems, it is imperative that they comprehend the subtle differences between each approach.

Traditional air supply scheme to the furnace
The term "traditional air supply" refers to the most popular method of supplying air—blown air—through the furnace’s lower section. Not only is this the most popular method of setting up the furnace’s respiration, but it’s also not the most sensible. The truth is that heat literally disappears into the pipe from the room where the furnace is melted when the summer passage valve is opened, which is also the moment when the stove produces its strongest thrust. Naturally, colder air starts to enter the room outside. Consequently, the room cools down and loses heat quickly.
An additional consideration is if the stove has a duct system, which could be used to draw oxygen directly from the street or from the basement. In this instance, there is no drop in room temperature during kindling, but there is also no reduction in thrust.
By decreasing the amount of air that is circulated inside the space, this creative plan helps you heat the room more efficiently and minimize heat loss. However, you won’t be able to save as much money if the furnace isn’t made to burn light gases.
Secondary air during combustion
Relatively recently, the concept of utilizing the anti-flow scheme of construction to guarantee the full combustion of hydrocarbons in the furnace has gained popularity. She is fully represented in solid-fuel heating boilers as of right now. However, using such a scheme proved to be much simpler for the metal; however, this technique is not always employed in brick furnaces.
Burning in brickwork
Nonetheless, the Finnish closed fireplace serves as a good illustration of how secondary air is used in brickwork to finish the combustion of light materials. A basic arrangement of primary and secondary supplies that includes space for burning out gases and oxygen in the firebox varies in a number of ways:
- For the combustion process, the direct supply of oxygen is constantly necessary – the overlap of oxygen supply leads to firing fire. For the process of gas burning, oxygen is needed starting from the moment the temperature rises to 600-700 degrees, then not immediately, after the start of the firebox;
- Through the open air, the air flows heated to room temperature or temperature, which corresponds to the room from where the fence is made. For secondary air, it is important that oxygen enters the combustion chamber already heated, and heated to a rather high temperature-about 500-600 degrees;
Therefore, in order to achieve full combustion of carbon monoxide, hydrogen n2, soot particles H (s-N), and atomic carbon C, it is imperative to guarantee the availability of the necessary volume of oxygen and to heat it to the ideal reaction temperature.
Understanding the core of this technology will be made easier by using the Finnish fireplace as an example of the air supply to the furnace. There is no blow, as firewood burns on the stove underneath the furnace, in contrast to a traditional firebox in the fireplace. The openings in the door serve as the direct oxygen supply. By the way, the doors have a few distinct features in their design, the most important of which is an adjustable grate that allows oxygen to enter the furnace.
Additional combustion chamber
The second element that deserves separate attention is an additional camera in which the final combustion of fuel occurs. It, as expected, is separated from the fuel with a fireplace tooth located almost horizontally. The second version of the fuel separation is a catalyst grill, which is warming up from the temperature of the flame in the primary firebox, serves as a temperature catalyst for the reaction in the secondary chamber.
But this chamber’s oxygen escapes through a tightly shut door. The supply is made through cavities in the metal frame of the glasses and in between the glasses themselves in the second chamber, but only if through openings are made for the furnace. Since the flow is designed to remove soot and soot immediately into the combustion chamber of light gas, this technique not only ensures glass transparency but also allows the air to be heated to the necessary 500–600 degrees.
The debate over proper furnace breathing vs secondary air supply is important when it comes to safely and efficiently heating your home. Both approaches are important for keeping a heating system effective and healthy.
The benefit of secondary air supply systems is that they increase the amount of oxygen in the combustion chamber, which encourages more thorough burning of the fuel and lowers emissions. Lower environmental impact and increased energy efficiency are possible outcomes of this. To guarantee peak performance, these systems must be installed and maintained carefully.
On the other hand, keeping the furnace’s breathing system in good working order means supplying enough air for combustion without generating drafts that might impede the heating process. This calls for careful consideration of the configuration and design of the heating system’s vents, ductwork, and other parts.
The decision between secondary air supply and appropriate furnace breathing ultimately comes down to a number of variables, such as the kind of furnace, the size and design of the house, and any applicable local environmental laws. A professional in heating consultation can help homeowners choose the best course of action for their unique requirements.
Whatever approach you choose, it’s critical to put efficiency and safety first when heating your house. Your heating system can function dependably and efficiently with regular maintenance, such as cleaning and inspections, keeping your house cozy all winter long.
