Dear Robert,
I read some chinese phd thesis who studied the gasification of chicken
manure.
The gas composition depends on : initial chicken manure size,
temperature, Ratio of air/chicken manure.
It seems that gas LHV is just a little lower than wood gas, see 4 MJ/Nm3.
The main problem of chicken manure gasification should be the control of
gas emission, since there are lots of N and ash in chicken manure.
So when you say : the gas comes out so clean, how you know? (since NOx
or SOx have no color I think).
If you like, I can send you some english papers about chicken manure
gasification.
Best regards,
Li

Dear List,
A while ago there was some interest in gasification of chicken manure.
As a request from a customer we have been doing chicken manure
gasification, in a very simple down draft gasifer at low temperature.
Chicken manure was mixed with rice husk, we dried and gasified. Since
I don't have the gas analyzer, anybody would know the composition of
the gas?
This is suppose to be a very big business and in need. Chicken farmers
do not need to much power to run the farm, but they need so much
energy to heat the chicks or the whole flack. In Europe vhere energy
prices are so expensive this might be the right way to concentrate on
some gasifier sales. The gas comes out so clean, it would be very easy
to clean and use in IC engines.
If any body has an idea or experience how to dry chicken waste, and
make a very simple control panel for the gasifier, I would appreciate.
Many thanks,
Robert
PS. Dough has always given us good advice. Now I know why my chemical
professor friend was using her dish washing waste fulid to spray the
vegetables and flowers.
