The TLUDs are so much superior over Rockets and three-stones for many reasons - for instance excess air control.

Ignition occurs first once the surface material of the fuel devolatilises and forms a gaseous flame. Once this flame is established the ‘flaming phase’ takes place characterised by the combustion of volatile products and their decomposition products (secondary pyrolysis products) as luminous diffusion flames. Thirdly the smouldering phase occurs which is characterised by heterogeneous char combustion and limited visible gas phase combustion. Classer et al. [17] have recently identified four combustion phases but in the present work we have used the simpler classification of the two major phases, flaming and smouldering because of the difficulty of distinguishing between the other phases.</i></div></div></div></blockquote><div><span class="Apple-tab-span" style="white-space:pre"> </span><b class="">[RWL: As I said I have not read any of these three carefully - but it would be interesting to hear from anyone on the list who can talk about the Classer reference to a fourth phase.</b></div><br class=""><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class=""><i class=""><br class=""></i></div><div class="">Gravimeteric measurements of particulate matter samples at an interval of 5 minute was done during a cooking cycle.

The results of this study suggest that EC and OC emissions from various solid fuels differ substantially in composition and relative proportion. <br class=""><div class=""><br class=""></div>Smoke emissions from the different fuels are also dependent on the phase of combustion. Roden and Bond, 2006 identified that cooking fires exhibited three general combustion phases, which were named as vigorous flaming, gentle flaming, and smoldering.<br class=""><br class="">a) Vigorous flaming is characterized by strong flames with a jutting appearance, resulting from rapid de-volatilization from the wood. It occurs shortly after the ignition of added wood.<br class="">b) Gentle flaming is characterized by smaller flames, lower emission of scattering and absorbing particles, and a gradual decrease in CO2.<br class="">c) Smoldering, occurs when the flames have extinguished.<br class=""><br class=""><br class="">Roden and Bond, 2006 studied the influence of flaming events and found that very dark particles with the optical properties of black particles are emitted during this phase. During the vigorous flaming phase, the emissions of particles are very high, especially dark, light absorbing particles associated with low instantaneous single scatter albedos. CO2 usually peaks toward the end of vigorous flaming. In the gentle flaming phase scattering and absorption coefficients were often similar in magnitude during this phase, indicating that both strongly absorbing and non-absorbing particles were emitted. Carbon monoxide concentration followed either the scattering or absorption coefficient. In the smoldering phase, light scattering increases sharply because flames are not consuming the volatile matter emitted from the wood, which recondenses into particles. Despite the lack of flame to create black carbon, these aerosols still have an absorbing component. CO emissions here are no greater than those of the preceding gentle flaming phase. The decreasing carbon dioxide concentration shows a drop in burning rate.<br class=""><br class=""><b class="">So during realtime emission measurement of stove, can we say that to determine </b><b class="">which combustion phase we are in, there can be two parameters to define that</b></div><div class=""><b class="">A) EC/OC ratio </b></div><div class=""><b class="">B) CO/CO2 ratio<br class=""></b></div></div></div></div></blockquote><div><br class=""></div><span class="Apple-tab-span" style="white-space:pre"> </span>RWL: Darpan - I am unable to get into your above further (being fully occupied with large scale biochar topics/promotion), but am impressed that you are so active in the topic. I think these three papers are addressing what happens, but less on why the emission differences happen as they do. Obviously there are huge differences in the hundreds of chemical compounds that are emitted and combusted at different times for a particular small solid biomass piece. I will never have the right technical background to answer the “why” question. Hopefully others on the list can chime in - especially as to how to construct a superior stove. The experimental evidence I have is that a TLUD that saves out the produced char is of the superior variety.</div><div><br class=""></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Again, thanks for your interest.</div><div><br class=""></div><div>Ron</div><div><br class=""></div><div><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class=""><div class=""><br class="">Regards</div></div><div class="">Darpan</div></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On Sat, May 20, 2017 at 10:26 PM, Ronal W.
