Somewhere there should have also been the name “English”. I took the three papers being discussed here (two in an Appendix) as being very good news for biochar. Three parts of the three reports (for me) need an explanation that probably only you can supply:</div><div><br></div><div> a. The char labeled “old” was clearly not as acceptable. The size distribution and the carbon content were different. Do you have an explanation? How could the carbon content be so low?</div><div><br></div><div> b. I had not realized you could produce char all the way from 500 C to >700 C. Is the former done at lower power levels (less primary air) or what? Can you “dial in” a desired char temperature? Over what range?</div><div><br></div><div> c. Is yours still the only known retrofit of a boiler going from combustion to pyrolysis?</div><div><br></div><div>Ron</div><div><br></div><br><div><div>On Dec 23, 2013, at 12:53 AM, Erich Knight <<a href="mailto:erichjknight@gmail.com">erichjknight@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr"><div><div>Thanks John,<br><br></div>This work with Burt's Greenhouse will go into my report to Richard Landis at DuPont & folks at ORNL Bio- Sciences.

</div><div><br></div><div>I've not read it yet. But the relevance to our work here in the Southeast is that there are a number of existing biomass boilers that could be modified and operated to co-produce biochar, just like Alex English did at Burt's Greenhouses. </div>
