I am working on a 100' oven with 5 zones. Each zone has upto 24 burners. 12 top burners, 6 middle & 6 bottom. Each zone has 1 damper (0% closed to 100% open, 4-20 ma) and 2 combustion blowers (Siemens drives) to regulate the gas to low, medium and high.
We have a themocouple to monitor the temperature in the exhaust duct for each zone.
Normally at the plant they go through a trial and error method turning the burners and on till they get the desired temperature and save this in a recipe.
Now they have requested it would be nice to put in the desired temperature and have the computer decide which burners to turn on and off.
I am thinking we will need mutible rtd's or thermocouplers to even start doing this type of process. This may let me achieve an even temperature in each zone.
Other than that, I have no ideal on the best way to achieve this. Anyone out there got any suggestions.
I will not be able to check back in till tommorrow night. These 12 hour days are getting old.
