What type of scrubber is commonly used in an incinerator?

1. Dry scrubber

2. Wet scrubber

3. Chemical scrubber

4. Mechanical scrubber

The correct answer is: Wet scrubber

In the context of incinerators, a wet scrubber is commonly used due to its effectiveness in removing pollutants from gases produced during the incineration process. Wet scrubbers operate by introducing a liquid, usually water, into the gas stream, where the liquid absorbs or reacts with pollutants, such as particulate matter, acidic gases, and volatile organic compounds. This process enhances the overall efficiency of pollution control by allowing for the effective capture of a wide range of contaminants. Wet scrubbers are particularly useful in incinerators because they can handle high volumes of gas and effectively reduce the emission of harmful substances into the atmosphere, thereby complying with environmental regulations. The moist environment also helps in stabilizing the dust and particulates, making it easier to collect and dispose of them afterward. In contrast, other types of scrubbers, such as dry or chemical scrubbers, may not be as effective given the specific demands and environmental controls required in incineration processes. Mechanical scrubbers, while useful in some scenarios, do not provide the same level of absorption or reaction with pollutants as wet scrubbers do. Thus, the choice of a wet scrubber aligns perfectly with the requirements of an incinerator setting.
