I haven’t discussed this with them but they did say that the heat load is the primary benefit of the system. Power generation is secondary. The university pays much more for natural gas than we would pay in Oregon at industrial rates. Plus the province has a carbon tax. So heating with wood is desirable. Perhaps for this they increased the size of the boiler. If I remember correctly the jacket water dries the fuel (in a Stella down flow belt dryer). The boiler is fed with engine exhaust and directly with gas from the gasifier. The gasifier can drive either heat, power or both. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Tom <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> gasification-bounces@lists.bioenergylists.org [mailto:gasification-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Thomas Koch<br><b>Sent:</b> Sunday, June 24, 2012 3:23 PM<br><b>To:</b> mark@ludlow.com; Discussion of biomass pyrolysis and gasification<br><b>Subject:</b> Re: [Gasification] 2 MWe Gasifier at University of British Columbia, Vancouver, Canada<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=DA style='color:#1F497D'>Hi Tom<o:p></o:p></span></p><p class=MsoNormal><span lang=DA style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Vonderfull to hear that good quality small scale gasification systems are being build. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>One of the challenges of small scale gasification systems are the low total efficiency. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>As I can read from their homepage it is a 2 MWel system that is also producing 9000 pound steam/hour and a total efficiency og 65 % <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>That gives a total fuel input of 7,5-8 MJ/s and 25-26 % electric efficiency and a total loss of 2,5-3 MJ/s. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Is it possible to say where these losses occur?<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Best regards<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Thomas<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Fra:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <a href="mailto:gasification-bounces@lists.bioenergylists.org">gasification-bounces@lists.bioenergylists.org</a> <a href="mailto:[mailto:gasification-bounces@lists.bioenergylists.org]">[mailto:gasification-bounces@lists.bioenergylists.org]</a> <b>På vegne af </b>Mark Ludlow<br><b>Sendt:</b> 24. juni 2012 23:46<br><b>Til:</b> 'Discussion of biomass pyrolysis and gasification'<br><b>Emne:</b> Re: [Gasification] 2 MWe Gasifier at University of British Columbia, Vancouver, Canada<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>Dear Tom,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Could you please clarify the steam output?

The system will supply just under 2 MWe net to the campus and 20,0000 pph steam to the campus heating system.
