What is the special spray gun for pulverized coal boilers?
The special spray gun for pulverized coal boilers is a kind of equipment that atomizes fuel oil (light oil, heavy oil, residual oil, etc.) to make the fuel oil into UM-level particles. Through air distribution and ignition, the fuel oil can be sufficiently burned. It is widely used in the boiler industry.
The special spray gun for pulverized coal boilers is mainly composed of the atomizing sheet, swirling sheet and diverter sheet. The working principle of the special spray gun for pulverized coal boilers is that the oil gathers in a circular groove through the small holes of the diverter sheet under a certain pressure, then passes the swirling sheet to the groove and enters the swirling chamber in the swirling center, finally generates high-speed rotating motion and sprays out from the center hole. The oil overcomes its own viscous force and surface tension under the action of centrifugal force and is crushed into fine oil droplets to form a conical atomization moment with a certain angle.
