<div>Here is a video I made of a TLUD Natural Draft stove that has adjustable Secondary Air. This stove is burning wood pellets. </div>
<div><br>
</div>
<div> The long wavy flames have as much secondary air turned off as possible. The tight blue flames are the result of almost maximum secondary air pre-mixed into the wood gas. During the video I am adjusting the air flow up and down to show the results
of different air/fuel ratios.</div>
<div><br>
</div>
<div>I believe these kinds of flames are only possible with very good pre mixing, which until now has been very difficult to control and keep lit. </div>

Dear Paul:<br>
<br>
In my view, the following aspects comes to mind when selecting a stove for<br>
a particular project:<br>
<br>
Cultural aspects: what type of cooking is done: frying, cooking, oven<br>
baking or baking over a griddle? The ergonomics of the cooking: at table<br>
level or ground level?<br>
<br>
Socio economics: will the community pay for the stove, partial pay or no<br>
payment at all? My experience is that when people do not pay anything, the<br>
care of the stove is more likely neglected, versus when there is some<br>
cost-sharing the beneficiary does take better care of the stove. We have<br>
had cases where we had to reinforce our casted concrete stoves against<br>
border breakage with a metal border, due to poor care by extremely poor<br>
beneficiaries.<br>
<br>
Geography: Is the weather cold (indoor cooking) or hot (outdoor cooking),<br>
and the ventilation patterns? Stove with lateral heat loss may be<br>
interesting for space heating, and for outdoors cooking a chimney may not<br>
be necessary.....<br>
<br>
Fuel availability: Will there be plenty of fuel available and at what<br>
cost? What type of fuel does the stove need? Some stoves, for instance,<br>
may need very small firewood sticks, and perhaps beneficiaries may be<br>
resistant to spending time splitting the wood. There are cases that<br>
beneficiaries modified the stove fuel entrance, for larger firewood, which<br>
changed the stove performance.<br>
<br>
Stove assembly: An off the shelf stove will be easier, faster and cheaper<br>
to install? or a localy built stove that may require a stove master to set<br>
it up?<br>
<br>
Just some quick thoughts about it....<br>
<br>
Rog?rio<br>
