RE: [Vo]:A practical LENR use
That's what the turbine is for: 300 HP -- we just replace the combustor can at the back. The working fluid is hot air. -Original Message- From: Jed Rothwell [mailto:jedrothw...@gmail.com] Sent: Wednesday, April 25, 2012 10:59 AM To: vortex-l@eskimo.com Subject: Re: [Vo]:A practical LENR use Hoyt A.

Re: [Vo]:A practical LENR use
The the 618°C temperature that you quote for the RR300 is MGT (measured gas temperature) which is actually the turbine outlet temperature. As such it will be 2-300° C below the Turbine inlet temperature. Small gas turbines like the RR300 with uncooled turbine blades have turbine inlet temperatures in the range of 850-1050°C. A gas turbine with 618°C inlet temperature would be lucky to reach 15% efficiency. And with a pressure-sapping heat exchanger to heat the air instead of a combustor (not to mention reduced turbine mass flow due to absence of fuel) the efficiency would likely be even worse.

RE: [Vo]:A practical LENR use
Thanks for the clarifications! It might still be feasible hopefully --maybe a ~3 MW reactor outputting 1000 °C . -Original Message- From: Robert Lynn [mailto:robert.gulliver.l...@gmail.com] Sent: Wednesday, April 25, 2012 12:19 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:A practical LENR use The the 618°C temperature that you quote for the RR300 is MGT (measured gas temperature) which is actually the turbine outlet temperature.
