AD, Kevin,
Bagasse typically runs between 45%-47% MC depending on the process in the sugar mills I have worked with. The moisture can be surprisingly uniform. 50% MC is easily burned in the boiler. As Kevin mentioned drying is an extra step that causes more cost and management problems than it is worth. Many bagasse dryers were installed in the 1980s. I think most have been abandoned. We dried bagasse to 15% MC to feed a gasifier for producing a gas to burn in a gas turbine. It handles well but the end product has to be worth the effort.

Drying it would cost money, improve efficiency, and result in a bigger waste bagasse pile.

Would anyone explain why they do not use dryer bagasse containing less moisture? Is it possible, that the water vapour in the bagasse reacts with the charred biomass to produce producer gas, thus adding to the fuel value of the biomass?

I posted the question in respect of those opinions given ( I don't have the band with to do the research right now myself) I do concur with your colleagues on their opinion the simplest is often the best. Thank you for the insight. Henri Naths Sent from my iPhone On Feb 21, 2011, at 6:31 AM, Anand Karve <[email protected]> wrote: Dear Naths, I am not an expert on engines of any kind.
