[Stoves] Green Steam Engine

[Kevin]

Dear Bryce

Certainly a "Closed Loop" or "condensing system" is more efficient than an non-condensing system. 

While the steam engine may not require Certification, boilers do, depending on the rules in a given Jurisdiction. While it is certainly possible to operate a steam boiler "in a back woods location that the Boiler Inspector doesn't know about", The Boiler Inspector will find out if there is an accident where someone is seriously injured or killed. 

Steam can kill.

If anyone is considering a "Steam Application" they should check with their Boiler Inspector, to confirm that he would be able to approve the Proposed Project.

Best wishes,

Kevin

  Hi Kevin, 

  Thanks for the lesson. Spent a little time googling and wikipediaing. I may have a slightly better grasp of the topic now.

  I did find something which may be worth looking at: 

  http://www.greenturbine.eu/en/product.php

  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. (http://www.greengen.be/) I wonder if they would sell to APL and/or if APL would have any interest in making a steam turbine genset...

  Bryce
