During the working process of the low-nitrogen burner, sometimes the burner emits black smoke. How to deal with such problems? First of all, we need to understand that gas burners are currently more popular combustion devices. It has a series of advantages such as high cleaning ring and high thermal efficiency. During use of this product, black smoke may appear. Does this mean that the equipment has been damaged and needs to be repaired?
There is a layer of diesel oil at the bottom of the heat exchanger, which cannot burn immediately at low temperatures. After normal combustion, the flame of the burner will heat and ignite the diesel oil below, and at the same time burn a large amount of diesel oil, forming a large amount of black smoke. When there is black smoke during the combustion process, the power should be turned off immediately and the work should be stopped immediately.
The diesel fuel injected into the gas burner is mixed and burned at the same time. When the air supply is correct, the emission of atomized CO2 and steam is colorless. When the air supply is insufficient, the incomplete combustion of diesel will lead to the formation of CO and carbon particles, resulting in black smoke in the exhaust gas. But if the air intake is too large and too strong, the wind will blow away the oil fume, and the oil fume will not have time to burn, forming white exhaust smoke.
The common cause of smoke exhaust is that the combustion intake valve is opened too small, and the white smoke is that the intake valve is opened too much. In both cases, the intake valve should be readjusted. During conditioning, the exhaust smoke can be observed when the conditioning damper is opened until the exhaust smoke is nearly colorless.
Another reason for the black smoke from the exhaust of the gas burner is poor atomization of the diesel oil. The oil mist contains large droplets, and the local combustion is incomplete and cannot be fully mixed with the air. The reasons for poor atomization of diesel oil are:
1) The aging or clogging of the nozzle seriously reduces the atomization ability of the nozzle.
2) The oil pressure of the oil pump is too high or too low. If the pressure of the pump is too low, the output pressure of the nozzle will be very low, of course, the atomization effect will be poor, but if the output pressure of the pump is too high, the injection pressure will also be very low. This is because the volume of the oil delivery pump is inversely proportional to the oil delivery pressure,
If the oil pressure is too high, the oil production will inevitably drop. Since the nozzle hole does not change, the pressure difference between the two ends of the nozzle will decrease, resulting in fuel emission often accompanied by black smoke, which is due to poor fuel atomization. According to the exhaust smoke color, the oil outlet pressure of the gas internal combustion engine oil pump can be adjusted. Adjusting the pressure of the pressure screw can rotate clockwise to increase oil production and vice versa. The normal pressure range of the oil pump is 0.98~1.18MPa, and no adjustment is allowed.
The gas burner presents black smoke during operation. At this time, do not rush to stop work to repair the equipment. You can try to increase the ventilation holes of the lotus root first to see if the color of the smoke changes. If you do not find professional maintenance personnel for maintenance. It is necessary to strictly abide by the instruction manual of the burner for testing.
The gas burner must not be disassembled randomly, and the professional advice and guidance of the manufacturer must be required.
