Hey there! As a supplier of Bioethanol Gas Fires, I often get asked about the color of the flame in these fires. It's a pretty interesting topic, and I'm gonna break it down for you.
First off, let's talk a bit about bioethanol. Bioethanol is a renewable fuel made from plant materials like corn, sugarcane, or wheat. It's a clean - burning alternative to traditional fossil fuels, which makes it a popular choice for modern fireplaces. When you use bioethanol in a gas fire, you're not only getting a cozy and warm atmosphere but also being more environmentally friendly.
So, what's the color of the flame in a bioethanol gas fire? Well, typically, a pure bioethanol flame has a blue - yellow color. The blue part of the flame is usually at the base. This is where the combustion is the most efficient. In this region, the bioethanol is reacting with oxygen in a complete combustion process. The chemical reaction here is producing carbon dioxide and water vapor, and the blue color is a result of the excited molecules in the flame emitting light at a specific wavelength.
The yellow part of the flame is higher up. This is because the combustion in this area is a bit less efficient. There might be some incomplete combustion going on, which means that there are still some carbon particles present. These carbon particles get heated up and glow yellow, giving that characteristic yellow hue to the upper part of the flame.
But the color of the flame can also be affected by a few factors. One of the main factors is the amount of oxygen available. If there's a good supply of oxygen, the flame will tend to be more blue. That's because the complete combustion process is being favored. On the other hand, if there's a limited supply of oxygen, the flame will have more of a yellow or even an orange tinge due to more incomplete combustion.
Another factor is the quality of the bioethanol fuel. If the bioethanol has impurities in it, these can change the color of the flame. For example, if there are some metal salts in the fuel, they can cause the flame to have different colors. Copper salts can make the flame turn green, and strontium salts can give it a red color. But usually, high - quality bioethanol fuels are pretty pure, so you'll mainly see the typical blue - yellow flame.
The type of burner in the bioethanol gas fire can also have an impact on the flame color. Some burners are designed to mix the bioethanol and air in a specific way to promote more efficient combustion. These burners will often produce a more blue - dominant flame. Other burners might be designed to create a more aesthetically pleasing, flickering yellow - orange flame, which can be great for creating a romantic or cozy atmosphere.
