What is the Combustion Process of Liquid Fuel
The liquid fuels used in industry include heavy oil and tar, among which heavy oil is the main fuel. When heavy oil is used as fuel, it can be directly burned in the furnace. The heavy oil is transported to the plant by an oil tanker (or pipeline), stored in the oil storage tank, and then pressurized by the oil pump to the oil burner. In the oil delivery pipeline, a filter is required to remove the mechanical impurities in the oil. When the heavy oil burns through the oil burner, it needs to spray the oil into a mist, that is, atomization. A heater shall be set in the pipeline to heat the heavy oil to reduce its viscosity to ensure good atomization effect and fluidity. In addition, the entire oil circuit system is also accompanied by steam pipe heating and insulation. The heavy oil enters the furnace (or separate combustion chamber) for combustion after passing through the oil burner.
In order to achieve full combustion of fuel, the first condition is to supply enough air and mix it with fuel evenly. Therefore, when atomized liquid fuel is injected into the combustion space, how to ensure a timely and correct supply of enough air and full mixing with it will be the key to ensuring full combustion of liquid fuel.
Generally, fuel burners equipped with swirling flow regulators are commonly used on oil-fired boilers. The burner is also called a burner, which is composed of an atomizer and air regulator. The function of the air regulator is to correctly organize the air distribution, timely supply the air required for combustion, and ensure the full mixing of fuel and air.
