Heavy oil burner is a combustion device specially designed for heavy oil with high viscosity and poor atomization performance to improve the combustion performance of heavy oil. It is mainly composed of heavy oil tank, diesel tank, oil filter, heavy oil make-up pump, heat exchanger, light and heavy oil switching valve, fuel pump, pressure regulating valve, burner and its transmission pipeline.

   Technical features:

   1. The flame stabilizer is used to maintain a stable vortex circulation at the root of the flame and reduce the rotation of internal air, so that the primary air volume can be reduced by half.

   2. The flame closing cover is adopted, so that the heavy oil entrained in the air flow can not be diffused arbitrarily to produce the brake effect, the flame shape is more reasonable, the high temperature at the kiln head is avoided, and the service life of the kiln mouth iron guard is prolonged.

   3. The external clean air has intermittent rectangular straight air injection, which is changed to annular gap injection after reaching the front end of the burner. At the same time, the area of the annular gap is increased, which can lengthen the flame and improve the average temperature in the kiln.

   4. The swirl blade is installed at the front end of the inner air duct, 2cm away from the front end of the outer air duct wall, which plays a role in closing the flame and avoiding high temperature at the kiln head. The first handle of the burner can be adjusted. The position of the swirl blade is positioned at 6 "of the scale when leaving the factory. The adjustment range is 0}6cm, and there is no negative value. The internal air swirl can only pull back and lengthen the flame.

   5. The central wind blows the high-temperature gas around the nozzle back, which not only cools the interior of the nozzle, but also cools the end face, so as to protect the burner head and prolong the service life of the burner.
