Charcoal

Charcoal Quality

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.

Biomass Densification

Biomass Densification, Previously: Mobile Pyrolyzer for a Biorefinery Feedstock, Jim Robinson, Conversion Processes, California, March, 2006, updated August, 2007.

Thank you for giving me publicity with your entry about my Biorefinery Feedstock process. I have change the title of my data sheet to Biomass Densification which I am attaching. My interests have changed to accepting pyrolysis which I had previously rejected because the pyrolysis oil had a pH pf 3,0 which caused a requirement for stainless tankers for transport. I have found 9i can send you a copy of the article)that catalytic pyrolysis with a HZSM-5 zeolite catalyst reduces the acid content by 80%

Sincerely,

Jim Robinson

MR Charcoal

Abstract: An exploration of a large scale Top Lite Up Draft (TLUD), fabricated from a recycled hot water tank heater.

Here, Mr Charcoal is running on loose switchgrass.

This is at the end of the switchgrass burn. I wanted to show the charcoal but it did not show up in the picture.

Gas-of-Fire 1000; architecture

This is a stratified (AKA open top) gasifier with divorced fuel magazine. To start with, I plan to just hand feed it. This version is constructed from a junked hot water tank, plus other misc. junk that I had in stock.
