What are the three essentials for combustion in an incinerator?

The correct answer highlights the three essential elements necessary for effective combustion in an incinerator: time, temperature, and turbulence.

Time refers to the duration that the waste material is exposed to the heat source during the combustion process. This factor is critical because it ensures that the waste has enough time to combust completely, which minimizes the production of harmful emissions and maximizes the efficiency of the incineration process.

Temperature is vital because it needs to reach and maintain a level high enough to ignite and sustain the combustion of the waste materials. Inadequate temperature can lead to incomplete combustion, resulting in the release of unburned pollutants.

Turbulence is an important aspect because it enhances mixing between the combustible materials and the air (oxygen), promoting a more efficient combustion reaction. Optimal turbulence ensures that all the particulates are sufficiently mixed and heated, which facilitates complete combustion.

Together, these three factors—time, temperature, and turbulence—are crucial for the incineration process to effectively reduce waste volumes and ensure environmental protection through complete combustion.
