Infrared heating method compared to air heating method
In industrial production, for some objects that need to be heated and dried, the air heating method is usually used, but with the development of science and technology, infrared heating in industrial production is more and more widely used, especially in the curing oven, infrared heating method has many advantages over the air heating method.
First. Energy saving
Infrared heating compared to air heating, its biggest advantage is to save energy. Because infrared heating directly to the surface of the object heat, through the form of radiation energy to the object surface heating, so that the object can also be heated inside. The air heating method needs to heat the air first, and then transfer the heat to the surface of the object, there will be a certain amount of energy loss in this process, so compared to infrared heating, the air heating method will waste more energy.
Second, the heating speed is fast
In the curing oven, infrared heating method compared to air heating method there is a great advantage, is the heating speed. Because the infrared heating method does not need to first heat the air to a certain temperature, but directly to the object surface, so the infrared heating method can be faster to heat the object surface to the required temperature, thus making the entire heating process more quickly.
Third, uniform heating
Compared with the air heating method, infrared heating method in the curing oven has another advantage, that is, to achieve uniform heating. Because the infrared heating method directly transfer heat to the surface of the object, so the object surface and internal temperature changes are more uniform, there is no air heating method in the local temperature is too high or too low.
Fourth, not affected by the wind
In the curing oven, infrared heating method compared to the air heating method has another advantage, that is, not affected by the wind. Because infrared heating does not require air as a transfer medium, so will not be affected by the wind. While the air heating method in the heating process, if the wind, it will make the transfer of heat becomes uneven, affecting the heating effect.
Five, more suitable for high-temperature heating
In some occasions where high temperature heating is required, infrared heating method also has obvious advantages over air heating method. Because infrared heating can directly transfer heat to the surface of the object, without first heating the air to high temperatures. The air heating method will not only waste more energy when heating at high temperature, but also cause more pollution to the environment, because the oxygen and nitrogen in the air will react at high temperature and produce some harmful substances.
Sixth, more space-saving
In the curing oven, the use of infrared heating method compared to air heating method has another advantage, is more space-saving. Because infrared heating equipment is small, can be installed on the top or side of the curing oven, will not take up too much space. Air heating equipment is larger and needs to be installed on the side or below the curing oven, which will take up more space.
In summary, infrared heating method in the curing oven has many advantages over air heating method, including energy saving, fast heating speed, uniform heating, not affected by wind, more suitable for high temperature heating and more space saving. Therefore, infrared heating method has become an excellent heating method in some occasions where objects need to be heated and dried, and can improve the efficiency and quality of industrial production.
