Speed never changes. If the LFTR c...That's correct. Speed never changes. If the LFTR can handle the rise and lowering of demand, the limiting factor is only the turbine's ability to handle that torque. Most modern turbines of the Rankine cycle can handle 10 to 20MW-per-minute load changes easily.<BR/><BR/>Newer yet-to-be-designed closed-cycle Brayton cycle turbines I can see having this capability built in.<BR/><BR/>I think you are actually raising and very important point. The ability to both load follow, change load, and, especially go to *minimum* load is a "product" that has immense value for any system operator. The LFTR having this ability is going to be a great 'selling point' for the technology. I think it needs to be emphasized more. Thanks for doing this.<BR/><BR/>DavidDWhttps://www.blogger.com/profile/03070034894266417461noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-66715388204362713912009-03-10T10:29:00.000-05:002009-03-10T10:29:00.000-05:00David, You are undoubtedly correct, A more accura...David, You are undoubtedly correct, A more accurate account then would be that 100% of potential torque is immediately available although most likely it would be applied gradually to avoid over stressing the system. The turbines would be kept spinning at times of no power demand by decay heat.Charles Bartonhttps://www.blogger.com/profile/01125297013064527425noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-31202261371558312572009-03-10T10:17:00.000-05:002009-03-10T10:17:00.000-05:00Charles, it is not that a LFTR can spin a turbine ...Charles, it is not that a LFTR can spin a turbine from zero to 3600 RPMs quickly.It is that it can provide the torque necessary to go from minimum load (as determined by the safe operation of the turbine...all of which have minimum load set points, usually about 20% of full load) to full load...but the turbine ALWAYS spins at either 1800 or 3600 RPMs because that is "the speed of the system".<BR/><BR/>DavidDWhttps://www.blogger.com/profile/03070034894266417461noreply@blogger.com
