    A SHORT answer to what could have books written about it.    I refer
    to this quotation that you provided from the paper:
    <blockquote type="cite"><i>Batch combustion in a fixed bed follows
        three major stages. Ignition occurs first once the surface
        material of the fuel devolatilises and forms a gaseous flame. </i></blockquote>
    <i>Done.   Yes, that is understood.<br>
      <br>
    </i>
    <blockquote type="cite"><i>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. </i></blockquote>
    <i>Note that they are discussing the UPPER flaming of the gases that
      have come from the raw fuel down below.<br>
      <br>
    </i>
    <blockquote type="cite"><i>Thirdly the smouldering phase occurs
        which is characterised by heterogeneous char combustion and
        limited visible gas phase combustion. </i></blockquote>
    Npte that they are now discussion "char combustion" which is
    occuring at the bottom of the now pyrolyzed biomass.<br>
    <br>
    THEREFORE, there is confusion between that is going on and where it
    is happening.  I do NOT like this terminology.   Instead, please
    consider:<br>
    1.  Ignition stage.   no change<br>
    <br>
    2.  FLAMING pyrolysis.   This is down INSIDE the fuel bed.   It is
    flaming because O2 is present as the pyrolytic gases are released
    from the fuel particle.(actually sort of glowing because the flames
    are VERY small.   Contrast this with NON-flaming pyrolysis which is
    pyrolysis as it occurs inside of a retort (where there is sufficient
    heat but no entry of O2).       Note that this is NOT referring to
    the flaming of the gases at the top of the gasifier (or even further
    away if through a pipe, etc.)<br>
    <br>
    3.  CHAR-gasifification.    (why call this "smouldering"?)    Note
    that the realtively small amount of gases being created are CO and
    they will cause VERY SMALL FLAMES (visible in a darkened room) if
    there is O2 where that CO is liberated.   But if no O2 or if cooled
    somewhat, that CO will not burn, and will become CO emissions.<br>
    <br>
    Personally, I will not be referring to "smouldering" as a combustion
    process.   It is too vague.  <br>

      <div dir="ltr">Dear Mr Larson
        <div><br>
        </div>
        <div>Thanks for sharing the research papers. What is unclear to
          me is the distinction of the flaming and the smoldering phase.
          <b>How do we know in an practical experiment that the flaming
            phase is over and is the beginning of the smoldering phase.<br>
          </b>
          <div><br>
          </div>
          <div>Mitchell et al., 2016 (The first and second paper shared
            by you in the trailing mail), in their study found that
            flaming phase emissions were much higher than in the
            smoldering phase. CO emissions are also dependent on the
            combustion phase. <b>So is emission measurement the a
              criteria to evaluate the distinction of a phase?</b></div>
          <div><br>
          </div>
          <div>Quoting a paragraph directly from the paper</div>
          <i>Batch combustion in a fixed bed follows three major stages.
            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. Elasser 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><i><br>
          </i></div>
        <div>Gravimeteric measurements of particulate matter samples at
          an interval of 5 minute was done during a cooking cycle. Each
          of the filter paper would then be analyzed for EC-OC . The
          EC/TC ratio is an indication of the different combustion
          phases (Mitchell et al., 2016). </div>
        <div>
          <div><br>
          </div>
          <div>Atiku et al., 2016 (by th same group from Leeds
            University) in their study found that the values of the
            EC/TC ratios for wood logs, torrefied briquettes, coal and
            smokeless fuel are highly dependent on burning conditions;
            namely the flaming and smoldering phases. The results of
            this study suggest that EC and OC emissions from various
            solid fuels differ substantially in composition and relative
            proportion. <br>
            <div><br>
            </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>
            <br>
            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>
            b)      Gentle flaming is characterized by smaller flames,
            lower emission of scattering and absorbing particles, and a
            gradual decrease in CO2.<br>
            c)      Smoldering, occurs when the flames have
            extinguished.<br>
            <br>
            <br>
            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>
            <br>
            <b>So during realtime emission measurement of stove, can we
              say that to determine </b><b>which combustion phase we
              are in, there can be two parameters to define that</b></div>
          <div><b>A) EC/OC ratio </b></div>
          <div><b>B) CO/CO2 ratio<br>
