1.Fuel quality
Heavy oil fuel composition is complex, the calorific value parameter is to ensure that the burner can provide rated heat prerequisites, kinematic viscosity, mechanical impurities and water content parameters directly affect the combustion adequacy; kinematic viscosity, mechanical impurity content and water content exceed the standard will cause the heavy oil in the burner nozzle atomization effect is poor, oil mist can not be fully mixed with air, combustion adequacy can not be guaranteed, to ensure the adequacy of combustion, in the selection of heavy oil must meet the above parameters requirements.
2.The effect of atomization on the adequacy of combustion
Fuel oil in the oil pump pressure or oil pump pressure and high-pressure air under the joint action of the atomization nozzle through the oil gun is fog spray, the size of the oil fog particles depends on the effect of atomization, poor atomization, fog particles, and air mixing contact area is small, the combustion adequacy is poor.
3.The effect of wind-oil ratio on the adequacy of combustion
The combustion of heavy oil is inseparable from the participation of air, and the air supply required by the oil burner is provided by the fan, and the cooperation between the air supply and the oil supply is called the air-oil ratio. The air supply should be adjusted in proportion to the size of the burner when adjusting the oil supply, in order to ensure the proper amount of air required for normal combustion, the proportion is out of proportion will inevitably bring about a decline in the adequacy of combustion.
4.Maintain the appropriate pressure
Maintain the appropriate pressure is conducive to shorten the fuel ignition delay time, extend the heating time, improve heating efficiency, and can ensure full combustion of fuel. The steady flame plate is generally made into a radial dispersion ramp outlet, which can form a strong rotating vortex when the air flows through, strengthening the fuel particles to continue to spread and mix along the axial and radial directions.
5.The influence of altitude on the adequacy of combustion
The design working environment of the conventional heavy oil burner is below 500 meters above sea level, when the actual use environment exceeds 500 meters above sea level, the density of air will drop with the rise of altitude, and the total amount of oxygen in the air provided by the same burner at work will be less than the amount of oxygen required for normal combustion, resulting in inadequate combustion.
