<span style="font-family: sans-serif; line-height: initial;">Stephen, by (EF) we mean the measured value multiplied by Lambda where Lambda is Excess Air factor plus 1 (ie total air demand). The figure you reported: 500, doesn't mean much to me until it is
undiluted. Maybe the EF value is 5000, not 500. We can only make useful comparisons between (EF) values. </span></div>

<div style="word-wrap:break-word">Hi Paul
<div><br>
</div>
<div>Thanks. OK I have measured a lot of pyrolysis devices and I can tell you they all produce CH4 and N2O as well as NOx (NO and NO2). Concentrations vary from well under 50ppm to over 500ppm for CH4 at 8% O2.</div>
<div><br>
</div>
<div>We have just finished measuring these parameters on Mr Khois stove DK-5 along with a new larger combine biochar/rocket stove I designed with Brenton Ladd in Peru for use in restaurants and will publish some time this year. We compared this with emissions
from an open fire. In this study we also measured dioxins and furans and PAH;s.</div>

I know of no such studies. And I expect to find none, either. NOx is not associated with TLUDs because the temperatures do not get high enough (that is my understanding, but not my field of expertise). And the same applies for CH4. The TLUD devices
that are the sizes of 200 L drums are constructed with a final flame as the gases exit. CH4 should not be able to survive that flame area.<br>

<div>Does anyone have CH4 and N2O emissions data or know of a thesis/ paper that details the quantity of CH4 and N2O from TLUD drum ovens?</div>

For over a decade I reported at each ETHOS meeting about advances in TLUD and other micro-gasification stoves of the previous year. For ETHOS 2015, there will be numerous independent presentations that relate to TLUDs, so I will NOT be summarizing about them.
But I will present the findings of those who cannot make it to the ETHOS meeting, or who only want a short summary of their work.<br>
<br>
If you are interested in having YOUR work about TLUD stoves summarized into my presentation, please send me appropriate information i the coming 2 weeks (by 16 January, please). You can send me:<br>
<br>
1. Basic info on your findings, designs, etc, including important information about stove acceptance if you have that, and I will make a PowerPoint slide or two.
<br>
<br>
2. Send me one or two PowerPoint slides (in .ppt or .pptx format, not as .pdf) that present your work.
<br>
<br>
Be sure to include your contact information on the slides. <br>
<br>
*********** Here is the Title and Abstract (at this time). I might pick up a co-author or two.<br>

Abstract<br>
</p>
<p>Numerous advances in TLUD and other micro-gasifiier cookstoves that occurred in 2014 have their own presentations at the ETHOS 2015 conference.<span>
</span>This presentation is an overview of <u>additional</u> work and status reports that otherwise would not be presented.<span>
</span><span> </span>With one or two slides from several TLUD stove projects, the range of diversity of approaches and underlying issues are seen on a world-wide basis. The presenter is in contact with potential contributors, organizing their inputs, and presenting
the diversity of results.<span> </span></p>

I am anticipating a wide variety of material to include. I hope that the Nurhuda / Differ activities in Indonesia are presenting, but if not, I will try to have a short summary of that effort. Same applies to Crispin with both Mongolia and Indonesia TLUD
information. Less likely to attend are people with TLUD efforts ongoing in India, Cambodia, Vietnam, Uganda, Kenya, South Africa, USA and El Salvador (I have direct contact with all of them), and am sure that 6 to 10 others might respond to this contact
requesting them to provide some short summary info. It will be SPECIFIC to TLUD and related micro-gasification. I am not trying to cover all types of stoves.
<br>
<br>
If you want to chat about this, I am at my home phone number below or by Skype or by email.
