HELIOSOLIDS® fluidized bed incinerator

The HELIOSOLIDS® fluidized bed reactor is a fluidized bed furnace for the staged combustion of wastewater sludge, bio-solids, industrial sludge and fine solids.

The reactor features integrated heat recovery, a stable fluidization and combustion process, and integrated flue gas cleaning.

Fluidized bed incinerator

A fluidized bed is a sand bed through which air is blown vertically from bottom to top at a speed that keeps the individual sand particles floating. The HELIOSOLIDS® fluidized bed reactor is a so-called bubbling bed, which means that the fluidization air speed is such that the particles are not carried away with the air. The sand bed behaves like a boiling liquid.

The product to be incinerated is introduced in the reactor just above the bed. The fluidization air is injected in the sand bed using a specially designed distributor plate that has to guarantee an even distribution of the air in the bed, and to avoid that sand flows back in the air duct.
