WebFluidized bed gasifiers Biowaste gasification HoSt acts as a turnkey supplier of (air blown) fluidized bed gasifier plants. By means of gasification biomass fuels can be converted … A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles. The resulting medium then has many properties and characteristics of normal fluids, such as the ability to free-flow …

WebIn slow pyrolysis, the most common reactors are drum, rotatory kilns, and screw/auger. In fast pyrolysis systems, reactors can be fluidized bed, rotating cones, entrained flow, vacuum, and ablative [16]. Typically, a pyrolyzer consists of a reactor, cyclone, and condenser. The cyclone separates solid products from liquid and gases.
