What are the characteristics of low nitrogen fully premixed surface combustion engine? Many companies that carry out boiler renovation have only a partial understanding of this and do not know what it is specifically for. They even say they only know that it is a combustion engine but do not know the specifics. Today, we will explain the characteristics of low nitrogen fully premixed surface combustion engines together.
1. Low thermal inertia, able to quickly heat up and cool down.
2. High thermal intensity and wide adjustment range. Foreign countries began researching metal fiber burners in the 1980s. According to Acotech’s data, when the excess air coefficient is between 1.1-1.3, the combustion conditions vary under different surface heat intensities: when the surface heat intensity is between 0.1-0.8W2, surface combustion occurs, and the surface burns red to 800-1000 ° C, emitting infrared rays; When the surface heat intensity reaches 0.9W2, a blue flame appears floating on the surface, and when the surface heat intensity reaches 5W2, it will not ignite. The metal fiber burner can also be made in a downward radiating form.
3. Under the condition of full air pre mixing (excess air coefficient of 1.1-1.3), there is no need for a cooling device for the head. Applications: Hot water boilers, drying equipment, industrial furnaces, engineering heating equipment.
4. Metal fiber carriers are more sturdy than porous ceramic plates, not afraid of cold water impact, and have a certain mechanical strength. They can be processed into any shape.
5. The content of CO and NOX in the combustion products is very low, with CO content below 40ppm and NOX content below 120ppm at high heat intensity (900 kW/m2).
6. Low noise.
I believe that through the above introduction, we have gained a certain understanding of the low nitrogen fully premixed surface combustion engine, at least its function. For the current national requirements for boiler renovation, the use of new technologies for low nitrogen fully premixed surface combustion engines is believed to be more favored by everyone.
