Grass for Power Generation
Johanes Judex, PSI April 2010

Hello everybody,

I have learned from this gasification network since three years and I learned a lot.
Thank you all, for sharing much information.

Most of the time I stayed in the background but now I want to post the link to my PhD thesis I did at the ETH Zuerich and Paul Scherrer Institut in Biomass Gasification.

I am not a native english writer so you will excuse the formal mistakes I made. Anyway I did my best to present:

Grass for power generation -- extending the fuel flexibility for IGCC power plants
http://e-collection.ethbib.ethz.ch/eserv/eth:1070/eth-1070-02.pdf

The outline of the work is as follows:

The fuel: natural native grass (extensive), wood
The gasifiers: bubbling fluidised bed (5-10kW) & single pellet reactor
The sampling: continuous wet scrubber
The diagnostik: GC, GC/MS, ICP-OES, TC, Karl-Fischer, Draeger tubes, SID
The parameters: Lambda, temperature, bed material
The goal: Stable operation, product gas clean enough for gas turbine applications
The result: you have to read it and decide for yourself

Well, I hope there is something for everybody in this work.

Cheers,
