[Gasification] ideal wood gas engine

[Tom Miles]

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.

Dear AD

 

One very simple explanation for not drying the bagasse partially is that
they have a gross excess of it, and it is a disposal problem. Drying it
would cost money, improve efficiency, and result in a bigger waste bagasse
pile.

 

Best wishes,

 

Kevin

Dear List,

The bagasse, which is burned in the furnace of a sugar factory contains
about 50% moisture. 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?

Dear Dr A. D. Karve 
Material handling is a definite factor with biomass with a moisture content
of 50%. 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.

Dear A D Karve

I need 100 hp @ 1800 rpm how much biomass would a sterling burn up per hr?
