Hydrogen elimination gas infrared heater for heat treatment of large components

Blue torch gas infrared radiator belongs to premixed gas surface combustion. The pre-mixed gas air mixture flows to the burner head and burns on the fabric surface layer with uniform air permeability. Combustion proceeds in two ways, infrared radiation and blue flame. Infrared heat radiation means that combustible mixture burns inside the fabric, the fabric is heated to incandescent state, and part of the heat is released by radiation.

The blue flame mode is that the combustible mixture burns above the fabric, the flame floats blue on the surface, and the heat is released by convection. Due to the uniform permeability of the material fabric and the uniform premixing of gas and air, the combustion is very stable and the temperature distribution is uniform, and there is no local high temperature, so the generation of NOx is suppressed. Premixing also has sufficient air supply, so the emission of C0 is also low.

First, infrared heater radiation principle

Any object radiates energy to the outside world. According to Boltzmann's law, the relationship between the energy radiated by an object and the temperature follows the following formula:

E=σ T4It can be seen that there is a fourth-power relationship between the energy and temperature of the object radiation, that is, the higher the temperature of the object, the greater the energy radiated to the outside.

The heat generated by the combustion of gas can raise the temperature of the object to 800-1000 ° C, thereby radiating intense infrared rays with a corresponding wavelength of 2-4μ m.

Second, infrared heating (drying) principle

Infrared is invisible light that travels straight at the speed of light and has a certain penetration. After infrared rays are absorbed by objects, they can be quickly converted into heat energy, which has a strong heating effect.

Different materials have different absorption rates for infrared rays. Water is one of the substances that can absorb infrared rays strongly. After water absorbs infrared rays, its temperature rises rapidly and evaporates. This is the principle of infrared drying. Infrared heating is several times faster than conventional hot air heating, so infrared can be used in situations where rapid heating and drying are required.
