Objective
The proposed study aims at investigating the fluidised bed combustion behaviour of corkwastes produced in corkprocessing industries which consume the wastes produced for the energy needs of the plants.
The existing systems used for burning wastes have several problems, particularly resulting from the fusion of the cork ash which leads to shutting down of boilers quite regularly for maintenance giving rise to production losses. Both bubbling and circulating fluidised modes will be investigated. Results of the proposed work could then be employed to establish conditions for the use of fluidised bed technology either for retrofitting existing boilers or the design of new boilers.
The specific objectives of the project are :
- the characterisation of the corkwaste as fuel with a particular attention given to its
ash composition and ash fusion point;
- the selection of most adequate feeding systems for corkwaste;
- the understanding of the combustion behaviour of corkwaste in fluidised beds
with the aim of determining the limits of operating conditions;
- the understanding of ash behaviour during the combustion to determine its
tendency to slagging and fouling;
- the determination of the levels of the pollutants resulting from the combustion
and definition of methods that could be needed to minimise the emissions of
potential pollutants to the atmosphere;
- based on the results, the evaluation of fluidised bed combustion techniques to be
used for both thermal and electrical requirements of corkprocessing companies
in an economically acceptable manner.
This will be the first time that FBC technology will be applied to corkwaste burning.
