    Time to heat a packed bed

    Hello, I'm trying to determine the center line temperature of a fixed bed reactor over time during heat up. The reactor has a 6" diameter and will be heated externally by electric heaters to 700C. Two heaters are currently being considered, one providing a heat flux up to 4 W/in^2 and another...

    Time to heat a packed bed

    Sorry about the last post. Autocorrect on my phone got me. It should read: Due to the nature of the actual setup, we may not be able to use a hot purge gas to help heat, so I would like to get a more conservative estimate by calculating conduction only. I'd imagine radiation will also be a...

    Time to heat a packed bed

    Yes, I agree this is not a very good way to heat. The application is actually somewhat different than I described, however this is the best way to think of it in simpler terms. Due to the nature of the actual setup, we may. It be able to use a hot purge gas to help heat, so I would like to get...
