This work describes a part of the design of a clean and energy efficient biomass stove both to cook and generate electricity for
developing countries.
For a simple and lowcost application of a ruralstove, commercially
available modules have been tested. The performance of energy
conversion of Bismuth Telluride TE modules has been evaluated
experimentally. The best power output of the system depends on the
heat transfer through both sides of the module; a particular attention
must be paid to the design of the heat exchangers. These results, with
the help of a simulation model, are the first step to propose a system
with appropriate locations of the modules.
Our study shows that the use of TE modules can be a very
convenient way. This would require the importation of the generator
module but the exchanger can be manufactured and assembled in
a local workshop. The produced electricity will run the fan in the cook
stove to increase the combustion efficiency. This will decrease the fuel
consumption and the emission level. Extra electricity will be available
to power LEDs.
Future work will consist in testing the TE modules into the
improved biomass stove
