Which type of incinerator uses graded silica?

The fluidized bed incinerator is designed to utilize graded silica as part of its operation. In a fluidized bed system, particulate material such as graded silica is used to create a bed that behaves like a fluid when air is introduced from below. This allows for more efficient combustion due to the increased surface area and mixing of the fuel, which leads to more effective heat transfer and uniform temperature distribution throughout the chamber.

This method ensures that the waste material is uniformly suspended and can be combusted at optimal temperatures, resulting in more complete combustion and reduced emissions. The properties of graded silica, such as its size and density, allow it to maintain the fluidized state, which is critical for the performance of the incinerator. This characteristic sets fluidized bed incinerators apart from the other types mentioned, each of which operates on different principles and does not necessarily incorporate graded silica in their design.
