Hazardous Waste Management Practice Test: Thermal Processes
Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 89% Most missed: “Residence time of waste in combustion zone is ________ seconds.”
Thermal Processes topics include: Thermal treatment, combustion technologies and energy recovery. Thermal treatment is a waste management process that uses heat to clean garbage. The goal is to convert waste into a stable, usable end product, while reducing the amount of waste that needs to be disposed of in landfills.  Thermal treatment processes include: Incineration: The combustion of hazardous materials at high temperatures to destroy contaminants. Incineration is done in an incinerator, a type of furnace that burns hazardous materials in a combustion chamber. Industrial plants for... Show more
