Model AZZD-500 - Burner
AZZD-500 type burner is an automatic, maintenance-free device used to burn fuel in form of sawdust briquette with granulation of 60 mm and of 100-300 mm in length. It cooperates with central heating boilers for solid fuels.
The burner's operation is automatic, and the device on its own lights up the fed briquette, controls the combustion process and damps the flame. The combustion process starts with feeding a fine pellet (with granulation of 8-10 mm) into the burner through a feeding channel, to which a briquette tank is connected with an elastic wire. The burner feeds the first fuel portion into the furnace, both primary and secondary air fans are started at low power, and the lighter located in the body glows the pellet with heated air. Once the desired glowing temperature is reached, the device should be switched to briquette feeding to enable the burner to enter the continuous combustion process. The lighter is turned off, the burner feeds the required fuel portion, fans blow the air for optimal combustion.
Once combustion phase is over, the device damps the flame. The burner stops feeding the fuel, and the fans damp the flame, while the furnace is cleaned from ash remains by the grate motion.
The device has a photocell installed so that the entire combustion process can be supervised.
