"And we still have the problem of a system calibrated at 450C being used at 1400C"
the main question is why this F******G reactor is at 1400C while it have less power in... OK, I'm not an expert, but this challenge my understanding. 2014-10-13 16:35 GMT+02:00 Alan Fletcher <[email protected]>: > The good news : In fig 6 the transmittance of alumina drops off by 5um,, > and drops off quicker at higher temperatures. > > The bad news : In fig 7 the emittance varies greatly by wavelength (1.0 to > 0.15), and also varies by temperature. > Levi et al do not mention the variation by wavelength, only temperature > (Fig 6, plot1). > > I don't know whether the IR camera system takes this into account. > > And we still have the problem of a system calibrated at 450C being used at > 1400C > ------------------------------ > *From: *"Jed Rothwell" <[email protected]> > *To: *[email protected] > *Sent: *Monday, October 13, 2014 6:23:11 AM > *Subject: *[Vo]:Determining the transmittance . . . of semitransparent > materials at elevated temperatures > > > A corespondent sent me this link: > > > http://www.eurotherm2008.tue.nl/Proceedings_Eurotherm2008/papers/Radiation/RAD_6.pdf > > He commented: "My interpretation of figure 6 is that the tranmissivity of > alumina goes down to zero.
