Abstract:

Fluidized bed gasifiers have been adopted for gasification of solid fuels like coal and biomass along with other gasification technologies like moving bed and entrained flow gasifiers. Fluidized bed gasifiers offers better mixing, uniform temperature and have ability to handle low quality fuels. Such units are industrially proven for combustion of solid fuels. Bubbling fluidized beds are commonly used for small to medium scale capacities. Gasification being order of magnitude slower than combustion process, handling it in fluidized bed gasifier pose many challenges as it may lead to loss of efficiency, unburnt carbon and so on. Hence study of fluidized bed gasifier is important from aspects like gas-solid hydrodynamics, reaction kinetics and inter-phase mass transfer that control the overall performance of the gasifier unit. In this paper, the objective of the study is to develop method for predicting the performance of the bubbling fluidized bed gasifier. This will critically evaluate the various correlations/methods available in literature which enables the research/ process designer to predict the performance of bubbling fluidized bed gasifier.
