So before I give you an overview, what is thermal radiation.Thermal radiation is a way of transmitting heat through electromagnetic waves.As long as the resistance of any object is higher than absolute zero, the thermal energy in the object will continuously radiate outward in the form of electromagnetic waves.Among them, only the infrared with a wavelength of 0.76-1000um plays a decisive role, and among them, only the infrared type with a wavelength of 2-6um is more likely to be captured by human beings, so this section of infrared wave value has the highest use value.Some applications of heating, drying and living in industry are also in this band.
So, what is an infrared radiator?To put it bluntly, the device used to produce infrared is called an infrared radiator.We commonly use electric infrared radiator and gas infrared radiator two categories.Gas infrared radiator can be divided into four types: radiation tube type, direct heating refractory type, catalytic oxidation type and surface combustion.According to the materials used in the radiant surface, infrared radiation is divided into three types of burner: porous meat porcelain plate type, metal mesh type and united city type.In addition to the difference of the infrared radiation plate, the structure of the gas supply allusion mixer is identical.
