Well, at a setting of 9 you have the same temp rise in 35 minutes as temperature fall in 35 minutes after power-off. ----- Original Message ----- From: Mark Iverson-ZeroPoint To: [email protected] Sent: Wednesday, September 14, 2011 4:55 PM Subject: RE: [Vo]:E-cat news at Nyteknik
JC stated: "(and note that this takes considerable time in the ramp up)" Where he is referring to the long time it takes to ramp up the E-Cat's internal temperature on startup. Mr. Catania, do you realize that the electrical power into the E-Cat's resistance heater was NOT started at 100%, it was started at a setting of '5' and RAMPED UP slowly over 40 minutes! Here is the time progression for resistance heater power. Timestamp PLC Setting DeltaTime (minutes) --------- ----------- ---------- 18:59 5 0 19:10 6 11 19:20 7 10 19:30 8 10 19:40 9 10 We know that the 'Setting' is referring to the duty cycle, but we do not know exactly what the relationship is. since 9 is the MAXimum setting, and Lewan states 'power was at this point constantly switched on', then a setting of '9' is presumably a 100% duty cycle. (?) Since the PLC's are programmable, we cannot assume that a setting of '5' is 50% or 60%; it could even be programmed to be 10% duty cycle. So no useful calculations OR conclusions can be made during this ramp-up phase. -Mark From: Joe Catania [mailto:[email protected]] Sent: Wednesday, September 14, 2011 11:58 AM To: [email protected] Subject: Re: [Vo]:E-cat news at Nyteknik I think it caused a rise. There is no rise. Its your imagination. The temperature at power off is too low and must be discarded. If I bring a piece of metal the size of an E-Cat to some temperature (and note that this takes considerable time in the ramp up) and then I cut the power, the temperature will not instantaneously drop. It will stay at the same temperature and decline slowly. There is much too much mass for what your talking about to happen. I have to laugh at the fact that if you saw the temp drop even a hundredth of a degree at power down you would have declared the thermal inertia regime over and the CF regime to have begun.
