Objective
PROJECT OBJECTIVES
This project aims to develop a comprehensive macroscopic model of ligno-cellulosic biomass gasification using the circulating fluidised bed process. The proposed approach would improve the present state-of-the-art by including in the model the heterogeneous fluid-dynamics and the finite and competing kinetic rates at all stages of the CFB reactor.
The main frame of the model will be gasification-oriented instead of gasifier-oriented, to maximise the flexibility and to ensure the applicability of the model to any design of CFB gasifier. The general structure will keep as open input at least: the design of the gasifier (shape and size), operating conditions (power, temperature, CFB mode, FB mode, equivalence ratio), wood fuel characteristics (kind, size, moisture).
TECHNICAL APPROACH
The proposed methodology consists of 3 steps:
. to identify the usability of the existing CFB gasifier models and to define a consistent approach of the coupled modelling-experimentation tasks, in terms of interaction between physical experiments and mathematical simulation . to perform targeted lab- and full scale experiments enabling to write sub-models and physically founded correlations, to be included in the main frame of the model
. to validate the final model by operating an industrial plant located in Zeltweg (Austria).
EXPECTED ACHIEVEMENTS
The resulting simulation tool would allow:
. the operators of CFB gasifiers, to optimise the management of their plants by control programs based on comprehensive modelling instead of parametric or empirical approach
. the manufacturers of CFB systems, to match their design to the specific applications of their customers, enabling them to produce gases of a targeted quality from various ligno-cellulosic biomass fuels (wood chips and bark of European wood species).
. the scientists to found their applied knowledge of the gasification processes on a comprehensive approach instead of on a parametric modelling and to improve their ability to provide realistic figures of CFB gasifier behaviour under innovative operating conditions.
