<p class="MsoNormal">Dear Terrence and Steven,<br>
<br>
I am glad to assist with the masonary heating system. Also nice to discover your initial and on-going interests:
<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Steven and I are focusing on biomass hot water heating systems for multi-urban, institutional and commercial project size
</span><o:p></o:p></p>
<p class="MsoNormal">About THAT topic, I have additional inputs to share with you. In a separate effort from my cookstoves work, a few years back my partner Paul Wever and I created Chip Energy (Illinois company) and developed the Chip Energy Biomass Furnace.
Beautiful for making the hot water heating systems!!! I can certainly be scaled up. Hard to make smaller unless the price does not go down much.
<br>
<br>
You can read about it at <a href="http://www.chipenergy.com">www.chipenergy.com</a> Four were made. One that is complete in a 20 ft shipping container is currently available (about US$45,000), and certainly can be seen in operation, including at Chip
Energy in Goodfield, Illinois. Produces about 50 - 60 KW thermal (>200,000 BTU/hr). Are you interested in the smaller end of the range of such water heating systems? Yes, it does produce charcoal, with even the ability to adjust char characteristics
related to the temperature of char creation. <br>
<br>
With that introduction to express my interest in your work, please send me information about your interests in biomass hot water heating systems. SIZE is a major distinguishing factor.
<br>

Paul<br>

<p class="MsoNormal">Nolbert and all,<br>
<br>
I just want to thank you and the others for looking into the use of TLUD technology for masonary heaters. Nice website for the MH Association
<a href="http://www.mha-net.org/">http://www.mha-net.org/</a> <br>
<br>
I would be delighted to work with you and the MHA in any ways that incorporate either TLUD stove technology or other methods (such as modified flame cap that is not yet being studied) that emphasize pyrolysis and therefore also have strong interest in the resultant
charcoal. Maybe there is or will be a small group of such enthusiasts. If so, count me in.<br>
<br>
I live in Illinois, but that puts me into the North America focus of your group!!<br>

<p class="MsoNormal">In the masonry heater industry we have a precedent from Austria. They have a proprietary calculator, that is accepted for certifying one-off heaters. The main nuts and bolts behind the math is the European EN-13384 chimney calculation standard.
You basically calculate the friction (pressure) losses for "worst case scenario" which is with a half load, in the summer, and verify that the appliance will draft properly. Damien Lehmann in France has developed an open source version and we are trying to
extend it to include additional heater types than only the Austrian style. Austrian heaters are "channeled", where the pressure loss calculation is based on the channel cross sections and length. In North America we have started building for example, a Russian
system that is based on buoyancy and has significantly less friction and that the Austrian calculator can't handle.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">After seeing Crispin's presentation on this at the Stove Design Challenge event in 2014 at Brookhaven Lab in NY, a team from the University of Buffalo did some work with it on a cordwood boiler. They found that
with a batch burn of standardized briquettes and a constant fuel composition assumption "...H2O is underpredicted at early times and overpredicted during the charcoal oxidation stage, resulting in a mean error of approximately 64%". The good news is that the
two sort of cancel each other out. I think the error in calculating overall efficiency was somewhere in the 3% range.<o:p></o:p></p>

CO dropped about 80%. We were a lot more excited about the PM drop, because this is the number that matters here to regulators. Europeans have told us that the United States is about 10 years ahead of Europe in air quality regulation. Largely due to California,
in particular Los Angeles. The Europeans are only just now recognizing the PM problem in urban areas from diesel and wood burning, and addressing this in their regulations.<o:p></o:p></p>
