Description: Ausgangssituation: Fuer die Vergasung von Biomasse in einer zirkulierenden Wirbelschicht (wie im BIOCO-COMB Projekt Zeltweg) fehlen geeignete mathematische Modelle. Loesung: Ein modifiziertes Zonenmodell soll eine Berechnung der Zusammensetzung des Produktgases ermoeglichen. Messungen liefern Daten fuer die Parametrierung des Modells. Innovation: Auch die Bildung von Methan und hoeherwertigen Kohlenwasserstoffen wird in das Modell inkludiert. Nutzen: Optimierung der Vergasung, des Entstickungsverhaltens (Reburning) sowie der Flammenstabilitaet bei der Nachverbrennung im Kohlekessel; das Know-how staerkt die Position auf dem Gebiet der Biomassenutzung.

Title: BIOGAMES: Modelling of biomass gasification for power systems
Description: General Information/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.
