The secondary burner burn the Exhaust gas from primary combustion chamber, this technologies make sure sufficient combustion, few black smoke and smell.  The updated incinerator technology focus on Exhaust gas treatment to remove Hazardous material and other purpose from incinerator, such as heat recovery (waste to energy), save fuel expenditure, PLC Automation operation.  In certain Developed nations, some new waste treatment method such as High-temperature cooking, waste carbonization, devastating sterilization technology is instead of incineration technology.
