<div dir="ltr">Crispin: <br><br>EPA NSPS are in g/hr basis, not g/t or kg/t. See <a href="https://www.gpo.gov/fdsys/pkg/FR-2015-03-16/pdf/2015-03733.pdf">https://www.gpo.gov/fdsys/pkg/FR-2015-03-16/pdf/2015-03733.pdf</a>.<br><br>I suppose for Single Burn Rate Heaters, g/hr can be converted to kg/t assuming kg/hr. See <a href="https://www.hearthandhome.com/news/2016-03-08/single_burn-rate_wood_stoves_new_again.html">https://www.hearthandhome.com/news/2016-03-08/single_burn-rate_wood_stoves_new_again.html</a>.<br><br>The target emission rate for new stoves beginning 2020 is 2 g/hr. The House <a href="https://www.congress.gov/bill/115th-congress/house-bill/1917/text">passed a bill</a> to extend the date to 2023; the Senate is yet to act, and I doubt it will become the law this year. <br><br>Also, the practical effect is to drive up the cost of forced air furnaces and hydronic heating systems. See Table 9, p. 13696. <br><br>With that kind of cost increase, either the old systems will continue to be in use (in existing buildings) or people will switch to gas and electric heating (for new homes). <br><br>And that too if states agree to implement the EPA NSPS on the original schedule. <br><br>In short, the whole multi-decadal exercise was a bureaucratic career project with negligible air quality impacts except in a few counties of the US. See Table 6, p. 13694. Annual reduction in PM2.5 emissions from wood heaters is expected to be measly 34 tons, and that from Single Burn Rate heaters 684 tons. <br><br>Wood is coming under attack in the UK as well. <a href="https://www.theguardian.com/money/2018/may/26/wood-burner-open-fire-pollution-cleaning-up-air-quality">Burning issue: Are wood-burning stoves going to get the chop?</a> Guardian (UK) 26 May 2018<br><br><br>Nikhil<br><br><br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><font face="georgia, serif">------------------------------------------------------------------------<br>Nikhil Desai</font></div><div><span style="font-family:georgia,serif;font-size:small">(US +1) 202 568 5831</span><font face="georgia, serif"><br><i>Skype: nikhildesai888</i><br></font><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>

<p class="MsoNormal"><span>I totally agree. It is kg/ton.

<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>JICA uses kg/ton which sort of makes sense if you are modelling airsheds, but it makes little sense as a stove rating. They have a stove testing facility in Ulaanbaatar in which they ‘test fuels’
which is a conceptually error in the first place. <u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>They have a “standard stove”. The problem is that if one finds a ‘bad fuel’ it can be placed into a different stove and it will be a ‘good fuel’. What then is the point of “testing fuels”??<u></u><u></u></span></p>
