Continues Feed Biomass Gasifier for Thermal Applications

A biomass waste wood gasifier plant, to provide thermal energy to dry 6 m3 of wood in 12
days. This system is developed by Biomass Energy Purworejo, Java Tengah, Indonesia for
small industry thermal applications to save fossil fuel, create energy from waste and reduce carbon footprint of the business and industries.

Your comments on the charcoal issue is right. This information is for the people who would be interested in charcoal making.

Not properly dried wood will never yield more than 20% charcoal and most of the pieces will be broken. Charcoal which is not broken in pieces, burn longer and gives more energy. In the market what is called Grade A charcoal, brings 30 to 40% more price than lump charcoal. What is most important today is try to make charcoal as clean as possible environmentally, even in traditional kilns.

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,

jO.hannes

Ultimate test for Producer Gas
Doug Williams, Fluidyne Gasification, New Zealand, August 5, 2007

Gasification Colleagues,

Since I began working with producer gas in 1976, the question of it's quality, and how to measure it in a way that clarifies it's purity, has never in my mind, been answered by gas analysis. I have seen many gas analysis presented to prove a gasifiers function, and therefore justify claims of how this gas can be used, but this can hide a multitude of problems within the gas making phenomena.
