Steam or MCF required for vulcanizer operation
Steam or MCF required for vulcanizer operation
(OP)
Thermodynamics question: I have a vulcanizer of a specific volume at room temperature and I am going to feed 80 psig steam to the vessel until the 80 psig is reached in the vessel. This pressure will be maintained for 90 minutes. I will be placing some foam material in the vulcanizer to cure. Periodically the valve feeding the steam will need to be throttled to reduce or add steam to the vessel. No condensate will be drained during the process. A 300 HP boiler is feeding the operation for 5 units. Calculate the energy require for one and I can take it from there.
Thanks for any help

RE: Steam or MCF required for vulcanizer operation
I didn't see such generosity in recent times, so, I will try to help you.
Check the specific heat of your foam and the cycle duration in which the foam is to be heated to curing temperature from whatever initial temperature. This is the maximum amount of load. From this point onwards, you have to just cater the heat losses from the equipment.
If your boiler capacity is sufficient for this duration then it is ok for the rest.

If this vessel is not internally insulated, you will need to add the heat load required to heat the shell shell and internals. That could be a much larger load that the product itself.
