Dear Tom, It looks like a HOT issue... Anyway, if you do not mind to help a little more: I have been working on cogen projects and I would be very pleased to know if there is any problem in measuring gas stream temperatures up to 850 oC. This is the usual maximum temperature downstream to burner at fired heat recovery boilers. Than you, Luiz Magri Rio de Janeiro __________________________________________________ Do You Yahoo!?
