the burner emitted black smoke

Natural gas burners normally operate safely and smoothly, but sometimes black smoke appears. The boiler burner relies on the mechanical energy input by the motor to increase the gas pressure and send the gas side by side. It is a kind of fluid machinery driven, if there is a fault will cause the emission of smoke can not be discharged into the atmosphere in time, thus causing the situation of black smoke. After individual tangential groove is blocked, the density distribution of oil mist is not uniform, the air quantity on the side with dense oil mist is insufficient locally, and the air quantity on the side with sparse oil mist is excessive, then the wind and oil mix, the condition is greatly deteriorated, the combustion situation is seriously deteriorated, and then the formation of black smoke.
