Thermal valorization of post-consumer film waste in

2019-7-8·Still in many places there are existing power plants which can be converted to burn biofuels with low investment costs. An efficient and proven way is to convert an existing boiler to fluidized bed combustion (FBC) or use atmospheric circulating fluidized bed biofuel gasification connected to an existing boiler.

fluidized bed boiler | BioEnergy Consu

The proportion of combustible material such as biomass within the bed is normally only around 5%. The primary driving force for development of fluidized bed combustion is reduced SO2 and NOx emissions from coal combustion. Bubbling fluidized bed (BFB) combustors are of interest for plants with a nominal boiler capacity greater than 10 MW th.

An overview of advances in biomass gasification

2016-6-2·Fluidized bed gasifiers come in three basic types: Bubbling fluidized bed (BFB): here, the biomass is fed from the side, and/or below the bottom of the bed, and the gasifying agent's velocity is controlled so that it is just greater than the minimum fluidization velocity of the bed material.
