Dear Nando,
Dear Dimitar Partenov,
Dear Carlos,
Dear all,
Thank you very much for your feedback. It is clear that the project is complex
and huge. It requires a complete study by a team of specialists. My group is
presently in a process of writing a preliminary report that the Ministry of
Energy of the Democratic Replubic of Congo will use to convince some financial
donors to finance the project. Your contribution is and will be appreciated in
that it will help us prepare this preliminary report.
Bear with me. I still have plenty of questions to ask but let me do it by steps.
Nando suggested a Francis turbine and a penstock of 1 meter diameter.
Dimitar suggested a Kaplan or a propeler turbine with siphon intake and a
penstock of 1.2 m.
Carlos suggested instead an axial "S" type turbine.
I did a bit of search on turbines and indeed all these turbines types fall in
the category of turbines that can be use for this head and flow ( H: 15m, Q:
10m�). I know that through your experience you have reasons behind your
selection.
I want to know the advantages and desadvantages of using the type of selected
turbines.
Since I want to have a spare unit also installed. Will it be cheaper to have
only one big turbine and a spare turbine or 2 running smaller turbines and a
spare one?
To run all the industrial machineries that are planned to be installed, almost
1MW of power will be needed. That is the reason why the selection of turbines
and generators must be so as to give at the other end a 1MW power.
Thank again for your willing to help
Willy L. Mwamba
