Answer: Option B
Solution:
Catalytic incinerators are advantageous as they require lower temperatures.In a catalytic incinerator, the gas stream is introduced into a mixing chamber where it is also heated.
The waste gas usually passes through a recuperative heat exchanger where it is preheated by post combustion gas. The heated gas then passes through the catalyst bed.
