A hazardous waste incineration system
By installing a steeply inclined ash hopper plate, a coking burner, and a combustion air inlet at the bottom of the secondary combustion chamber, the problem of ash and slag coking and blockage in the "rotary kiln + secondary combustion chamber" system was solved, enabling smooth ash and slag discharge and efficient system operation.

AI Technical Summary
The existing two-stage combustion system of "rotary kiln + secondary combustion chamber" is prone to coking and accumulation during use, which can lead to blockage of ash discharge port or exhaust port.
A smooth ash hopper plate with a large inclination angle is installed at the bottom of the secondary combustion chamber, and a coking burner and combustion air inlet are configured. The surface of the ash hopper plate is heated by high-temperature flue gas and flame, and air is supplied to the bottom of the secondary combustion chamber through the combustion air inlet to prevent ash from coking and blow it down to the ash discharge port.
It effectively prevents ash and slag from caking and accumulating on the ash hopper plate, ensuring smooth discharge of ash and slag, avoiding blockage of the discharge port, and improving the system's working efficiency and reliability.
