<p> </p>
<p>Second, studies have shown that the performance of EPA-certified wood stoves, especially with catalytic reactors, <a href="http://permanent.access.gpo.gov/websites/epagov/www.epa.gov/ORD/NRMRL/Pubs/2001/600R00100Front.pdf">deteriorate over time</a>.</p>
<p>Thus, the wood stove data reflect a ‘best case scenario’ of <strong>new</strong> stove performance under laboratory conditions.</p>
<p><strong>Natural gas and propane fuels, defined by ASTM standards, burn much more cleanly than wood, leading to near-zero particulate emissions.</strong></p>
<p>Wood is largely undefined. It has varying quality, composition and water content leading to varying burn rates and varying particulate emissions.</p>
<p> </p>
<p>Table 6 shows the low PM emissions of 2 g/h can be achieved, if the flyash portion of the ash is 3% or less of the total ash content of the wood; 97% would be in the bottom of the stove. <strong>All that during steady conditions near rated output, in a laboratory, with a prepared fuel sample.</strong></p>
<p> </p>
<p>The PM emissions for the 80% efficient stove would be 1000000/50000 x 1.98 = 39.6 g/million Btu, or 0.087 lb/million Btu.</p>
<p> </p>
<p><strong>NOTE</strong>: Medium-size hot water boilers, with cyclonic separators to catch particles larger than 5 micrometer followed by fabric filters to catch particles smaller than one micrometer, to heat a college campus, typically have less than 0.020 lb/million Btu.</p>

<p>The gas pipeline and pumping station should go forward, because nuclear plants will be closing by the time all is built. </p>
<p>The gas would be used to generate low cost electricity, at about 5 c/KWh to replace the low cost nuclear electricity.</p>
<p>The gas electricity would not be variable, not be intermittent, unlike wind and solar electricity.</p>
<p>Wind and solar electricity require huge subsidies plus they are variable and intermittent and COULD NOT even exist on the ne grid…</p>

<p>Wind and solar electricity require huge subsidies plus they are variable and intermittent and COULD NOT even exist on the ne grid without using the other generators as a crutch, plus their junk electricity is much more expensive, about 9c for wind and 11c for solar per kWh.</p>
<p>The people who oppose the gas line and the pumping station are seriously deranged in their thinking, and likely have not a clue regarding the analysis and design of energy systems.</p>

<p>Mills actually showed leadership on this issue earlier in the year. She did her homework, did the math, worked for an even better deal. The knee-jerk reaction to NECEC is naturally against, but considering the alternatives, the demand, and the impacts vs benefits, she made the right call. And she advocated for it. Now apparently she will play Pontius Pilate as she stands before an uninformed, emotional rabble. Wimp.</p>
