<br>I think this discussion of "boiler inspectors" may not be appropriate for commercial systems which integrate that steam turbine device, if for no other reason than that would be a self-defeating activity. I would imagine that the only way they could be successful would be to meet UL and CE standards for selling steam devices to the unwashed masses (like espresso machines).<br>
<br>It's not like it's a choice between risking death or not. Risk a steam explosion or risk a natural gas explosion. Or an electrical fire. Or CO poisoning. Or chimney fires. Furnaces manage large energy fluxes, and large energy fluxes have the potential to go sideways. Presumably this enterprise will only take off if the risk can be mitigated to a similar level.<br>
<br>But if your point was "don't screw around with steam on your own", it's well taken. :) Rest assured that was never my intention.<br><br>Bryce<br><br><div class="gmail_quote">On Wed, May 15, 2013 at 2:58 PM, Kevin <span dir="ltr"><<a href="mailto:kchisholm@ca.inter.net" target="_blank">kchisholm@ca.inter.net</a>></span> wrote:<br>

<div><br></div></div><div><div class="h5">Hi Kevin, <br><br>Thanks for the lesson. Spent a little time
googling and wikipediaing. I may have a slightly better grasp of the topic
now.<br><br>I did find something which may be worth looking at: <br><br><a href="http://www.greenturbine.eu/en/product.php" target="_blank">http://www.greenturbine.eu/en/product.php</a><br><br>These
appear to be self-contained turbines with a closed loop steam/feedwater
condenser system at 1.2, 2.4, and 15 kW. Steam is supplied at ~5 bar and the
condenser side is ~.1 bar. They sell primarily to systems integrators, one of
which makes a CHP wood pellet furnace w/cogen. (<a href="http://www.greengen.be/" target="_blank">http://www.greengen.be/</a>) I wonder if they
would sell to APL and/or if APL would have any interest in making a steam
turbine genset...<br><br>Bryce<br>
