What is the principle of a fuel combustion engine?

The principle of this equipment is generally that heavy oil will be divided into two paths into the burner. These two channels are called swirl oil and axial flow oil. Let me put it this way, it's like the internal and external air in a burner. Among them, the swirling oil will present a circular distribution when it is outside. And the axial flow oil presents a columnar straight jet flow in the middle.

Only these two streams of oil will blend together at the nozzle of the spray gun. Afterwards, it will enter the kiln through the nozzle of the atomizer. And this atomizing plate will also be divided into many types due to the different spray holes. Generally, during the heating and feeding process, the corresponding specifications of atomization plates will be replaced based on the actual situation. At the same time, the structure of the burner at the kiln tail will also be the same as that at the kiln head. However, at this time, his internal wind ratio is greater than the external wind.

The difference between oil inlet pipes and kiln head burners is that one is for oil inlet and the other is for oil return. A typical kiln tail burner will use 8.4mm atomizing plates.

In addition, in terms of the working principle of fuel burners, flame stabilizers are also used to maintain a stable vortex circulation at the base of the flame, causing the rotation of the entire internal air to decrease. The main principle of doing so is to reduce the air volume by half.

During the operation of the burner, a flame hood is also used. This principle is to use the flame hood to prevent the heavy oil in the airflow from overflowing and causing a negative effect. Make the shape of the burning flame reasonable and delay its service life.

You will also find that the central wind will blow away the high-temperature gas around the nozzle and push it back. This can cool the inside and end face of the nozzle. It can protect the head of the burner and extend the lifespan of the fuel burner.
