Which of the following describes Air Curtain Incineration?

• A. portable incinerator that is fuel intensive and doesn't kill all micros
• B. an industrial scale stationary incinerator with low energy use
• C. a water curtain barrier to reduce emissions
• D. a method of burying waste

Answer: (B)

Air Curtain Incineration uses a high-velocity curtain of air to create a barrier around the waste being burned, which confines the combustion zone, improves mixing, and helps contain emissions. This setup is typically implemented in an industrial-scale, stationary incinerator designed to achieve efficient destruction with relatively low energy input compared to portable, fuel-intensive systems. It is not a water curtain barrier, nor simply burying waste, and it isn’t a portable unit. So the best description is an industrial scale stationary incinerator with low energy use.
