What is an infrared burner?

An infrared burner is a type of radiant burner, also known as a schwank burner, and is a type of radiant burner. It has a cast body with a ceramic combustion plate. Direct heating can be performed by surface combustion using only gas, and combustion can be performed in any direction. Infrared radiation can be easily emitted without the need for fans, blowers, heat exchangers, etc.

How to burn an infrared burner

The gas jet from the nozzle sucks in almost the theoretical amount of air, mixes it at the venturi throat, and burns it. This is called the natural suction combustion method.

What is infrared light?

It is a type of electromagnetic wave like light and radio waves, and what appears orange is only a small part of the electromagnetic waves emitted by an infrared burner, and infrared rays themselves cannot be seen with the naked eye. The wavelength of the infrared rays emitted has the highest radiation intensity, and has a particularly high absorption rate for water, making it the most effective for drying.

Wavelength characteristics of infrared burner

The highest radiation intensity is shown at 2.8 μm, and a peak due to CO2 radiation appears at 4 μm. Looking at the absorption rate of the water film, it can be seen that radiation of 2 μm or more is easily absorbed by water. Therefore, it can be understood that infrared rays with long wavelengths of 2 μm or more are effective for drying, and that infrared burners are suitable for drying.

What is a ceramic plate?

It is a ceramic plate with multiple flame holes of about 1mm in diameter and unevenness on the surface to increase radiation efficiency and make the surface red hot, reaching temperatures of 800°C to 900°C. The size is 46mm x 67mm per piece, and the combustion amount per piece is 420W (360kcal/h).

What is a radiant burner?

A burner that transfers the heat generated by combustion to a solid, raises the solid to a high temperature, and uses heat radiation from the solid. There are various methods of transferring heat from the flame to the solid, and the burner structure is determined by that method.

What is combustion?

This is a reaction in which fuel combines with oxygen in the air to become carbon dioxide (carbon dioxide) and water, and at that time a large amount of thermal energy is released. This is a chemical reaction called an oxidation reaction.

What is an explosion?

An explosion is a very rapid combustion that causes rapid expansion and mechanical force, which moves the surrounding air and produces an explosion sound. Blow things up at the same time. In other words, the force of explosion is generated. It is the same thing as burning, but thermal energy is converted into mechanical energy through the expansion of gas, which is an explosion.

What is air ratio?

In order to completely burn the fuel, more air than the theoretical amount of air is required.The ratio between the theoretical amount of air and the actual amount of air is called the air ratio. In addition, the combustion status of combustion equipment can be determined by the air ratio.It is highly efficient to always burn at an air ratio of 1.0, but in reality it is difficult to maintain 1.0, so it is possible to burn at a slightly higher value. There are many. If the air ratio is larger than 1.0, excess air is being supplied, resulting in increased exhaust gas heat loss; if it is smaller, incomplete combustion will occur due to lack of air.

What is the theoretical air volume?

This is the amount of air theoretically required to completely burn 1m3 of gas fuel.
