When the rotary kiln incinerator is working, the furnace body drum is rotated, and the material is brought to the upper part of the cylinder by the high-temperature resistant lining plate on the inner wall, and the solid waste falls due to its own gravity. The solid waste rolls up and down in the cylinder and is in full contact with the air. Complete combustion is carried out through three stages of ignition, combustion, and burnout.

When the rotary incinerator starts to work, the solid waste is sent into the kiln from one end of the drum, and the hot flue gas is used to dry it first. During this period, the temperature in the furnace continues to rise. When the ignition temperature is reached, the solid waste starts to burn. With the rotation of the cylinder, the solid waste is burned out in the rotary kiln, and finally, the ash is discharged at the outlet of the cylinder.

When the water content of the solid waste is too large, a grate can be added to the rotary kiln incinerator process, that is, the second combustion chamber link. The flue gas discharged from the drum of the rotary kiln enters the second combustion chamber, where it is mixed with the air of the second combustion in the second combustion chamber for full combustion. After the secondary combustion process, all the flue gas can be burned, so as to achieve the goal of safe exhaust gas emission.

ROTARY KILN INCINERATORS are typically applied in the following KEY MARKETS:

• Medical and infectious waste incineration,
• Thermal desorption (soil cleaning),
• Hazardous waste incineration, including:
• Solid wastes,
• Sludge, slurries,
• Combustible liquids,
• Waste waters,
• High chlorinated hydrocarbons and PCB’s,
• Petrochemical wastes,
• Refinery wastes,
• Pharmaceutical wastes.
