<br>
<br>
Recommended air changes per hour in UK see to be 7-8 but this is<br>
probably more to do with preventing condensation from cooking,<br>
presumably with a flueless biomass cook stove it would need to be much<br>
higher, with a chimney I would expect it to be similar. Many kitchens<br>
will use a natural gas hob which is essentially flueless but clean<br>
burning.<br>
><br>
><br>
><br>
> Of particular importance are animal oils (fish for example) that are over-heated and evaporated. They will be high in BaP and other PAH’s.<br>
<br>
Yes this will come from partial oxidation, from flame grilling or as<br>
you previously pointed out where fat drips onto coals.<br>
><br>
><br>
><br>
> I was looking at the Kyrgyz Republic indoor air quality measurements from Fresh Air, Netherlands. It is rare to find a home that is below 25 µg/m3 even after installing a good stove.<br>
<br>
...but is 25µg/m3 the target we should be aiming for, I realise this<br>
is the level the World Health Organisation say but how practicable is<br>
it given your next paragraph?<br>
><br>
><br>
><br>
> Boots on the floor, smoking and cooking provide almost 100% of the IAP once the stove is taken care of.<br>
<br>
This is very much what I see at home, around 5µg/m3 quiescent state<br>
but when I walk into the room I notice a temporary rise to over<br>
10µg/m3, some of this may possibly be from particulates released into<br>
the local atmosphere by *my* chimney as I heat with wood, as well as<br>
background particulates and dust from my working.<br>
<br>
><br>
><br>
><br>
> As for the use of electrostatic precipitators and catalytic converters, they have both been promoted recently in Ulaanbaatar at a cost equal to or above the cost of providing a highly advanced new stove. In other words they are willing to spend more money to clean up emissions instead of preventing them in the first place.<br>
<br>
Yes I cannot see this being a sensible use of the money, nor fitting<br>
filters like a diesel car has to have now in UK (they have a back<br>
pressure which could not be overcome with natural draught).<br>
<br>
><br>
> Run properly the PM output is about 0.006 g/kg burned. Run badly it is about 4 or 5 times that: 0.030 g/kg. It is not worth spending hundreds of $ per installation to reduce that further.<br>
<br>
This will be coal burning then?<br>
><br>
><br>
><br>
> I see one of the stoves at the competition in DC reached 0.42 with wood. That’s pretty good.<br>
<br>
So is it a sensible target, 0.42g/kg of fuel burned? If we assume<br>
150% excess air (or more as long as it's known) we can relate that to<br>
a particulate concentration in µg/m3 of the stack emissions.<br>
<br>
...and yes Nikhil I realise I am being deterministic where you<br>
consider it is meaningless but I still feel targets are needed.<br>

This is an annual event with a stove-oriented parallel session providing an opportunity to present research, designs and thinking relevant to cooking and heating.<br>
All papers are reviewed and published.<br>
See you there!<br>
Crispin<br>
