Furnaces with fluidization beds are often used to incinerate waste or sludge from wastewater treatment plants. The principle of fluidized bed combustion is to "heat" a bed of sand and put the sand particles in suspension by a system of air injection nozzles. The combustible material is introduced into the bed where the high temperature of the sand ignites the material, the active movement of the particles of fluidized sand, completes the incineration of the combustible materials.

The Multistage Centrifugal Compressor supplies the air that fluidizes the sand bed. This air is also used for the supply of oxygen necessary for the combustion of waste products. The performance curve of our Compressor covers a wide range allowing a variable flow rate that can be adjusted depending on the amount of waste to be incinerated. Our Compressors are also used to supply air to the burner used to heat the sand bed.
