Distribution of secondary air from burner blasting

Distribution of secondary air in the blasting of the burner 　　 There are two types of secondary air distribution after blasting: one is free distribution, and the other is evenly distributed according to fire holes. Free distribution is the secondary air forced by the blower to be freely distributed to the fire holes, and there is a problem of uneven air distribution. The uniform distribution of the fire holes makes the secondary air forced by the blowing device evenly distributed into the fire holes as needed. Under the same test conditions, these two solutions are verified by the following data: 　　 However, the free distribution is simpler than the fire hole distribution structure, and the cost is lower. The size of the secondary air directly affects the excess air coefficient. A large excess air coefficient leads to an increase in the amount of smoke discharged, and the heat loss of the smoke is high, resulting in a decrease in thermal efficiency. Therefore, the amount of secondary air is also an important factor affecting efficiency. The following experimental data are obtained through experiments to force different amounts of secondary air to affect the thermal efficiency: 　　 Therefore, the control system of the blowing equipment should consider the supply of air volume, and the air volume supply during ignition should also be considered to avoid difficult ignition. Through the above analysis of several types of blasting burners, structural principles and test data analysis: 　　 1. The burner used in the blast-type auxiliary air household gas stove and the blast-type auxiliary secondary air household gas stove can achieve the purpose of improving thermal efficiency , But the blast-type auxiliary secondary air burner has excellent performance stability. In the explosive style, the air burner is supplemented once, and its application is stronger. Through a reasonable design, the explosively supplemented secondary air burner can also burn normally when the blasting equipment stops working. The blower equipment of the blast type gas-filled burner stops working and cannot burn normally.　　2. Secondary air distribution after blasting: the fire hole distribution is better than the free distribution performance, the burner working condition is better, and the thermal efficiency is higher.　　3. Control of the secondary air volume after blasting: The secondary air volume directly affects the excess air coefficient and the thermal efficiency. Excessive air ratio will reduce thermal efficiency. To If you are interested in gas oil burners, please contact us for a quote!
