Improvement of Thermal Processes for Using Residues from Bioethanol and Sugar Production in Brazil: Experiments and Proposed Optimization Measures

الملخص EN

Within a national funded Brazilian-German cooperation project ASHES, the thermal utilization of bagasse and other residuals from the sugar processing industry was examined.

The characterization of the ashes was also performed but it is not in the focus of this paper.

To determine the relevant combustion parameters, tests were carried out in a laboratory-scale, fixed bed reactor (KLEAA) at KIT-ITC.

Subsequently, Fraunhofer UMSICHT carried out tests in continuously operated combustion plants with different plant sizes of 30 kW, 100 kW, and 440 kW.

All relevant compositions were analyzed by CUTEC.

The primary objective was to gain knowledge regarding the combustion and emission behavior of the fuels.

These findings were used to identify optimization potentials at various points and elaborate concepts for their improvement.

In the next steps of the project, optimization of these concepts will be the focus.

In cooperation with the Brazilian project partners, several of them should be implemented into practice after the project.
