Nudge and wait is the only way with an oil burner - maybe with two or even three different rates. PID no good for this.
Thanks for the input chaps. I think "timgunn1962" hit the nail on the head with the above quote. I am restricted to single phase so running 10KW of electric elements is not a viable option. I have nearly finished building an oven 2x1x1m and was intending to heat it with a Riello RDB1 burner. To the best of my knowledge the temperature is not super critical (I am no expert at powder coating) I believe 180-200c would be more than acceptable. I have been playing with one of the Inkbird PIDs and from what I can see I am going to have to use it as an On/Off controller and somehow get around the fact the burner wants to purge for 20s before firing. If not I will need another way of controlling the temperature. I will get the burner into a position so I can test fire it tomorrow.If adding PID control is something that is only being considered as a "final touch", I'd have to say you've probably underestimated the task.
AFAIK that burner is only single stage (on or off) so will be impractical to control directly.was intending to heat it with a Riello RDB1 burner.
Oil burner into a domestic type boiler, with a radiator and fan to circulate the air and extract heat from the boiler water. You can pid the fan if you want, once up to temp would work a treat.
200 degrees C? Crikey, are you sure? You won't need much control for your burner unless the insulation is good. Either way you need an interface between the burner and the oven, so could use a stainless heat exchanger before the chimney, again with on off for the burner from a local thermostat, speed control the fan.Thanks for the input chaps.

I am following as well but I would not be going oil fired as I know nowt about it. I dont have gas in the garage so looks like leccy for me. Why do you need 10K of heat?Following this with interest, Have the same type of oven build in mind. Galv steel sheet frame, rockwool insulation etc. I have a lot of old chicken shed gas burners, with High calorific output, but don't want the complications of controlling temperature on the gas, so was thinking of using them for taking it from ambient to near final temperature, then shutting them off on solenoids and using small electrical heaters to do the final trimming / maintaining temperature. That would be far simpler to do. Was figuring that as long as the unit was well insulated the actual thermal capacity at the upper end shoudl be relatively easy to maintain, if the gas had the initial high load to raise the temperature.
haven't built it yet, so still in theoretical stages at the moment, but on paper (or in my head) it works. May give you more options.
Yes it sounds a lot to me?I am following as well but I would not be going oil fired as I know nowt about it. I dont have gas in the garage so looks like leccy for me. Why do you need 10K of heat?
Just goggled it - cure is 200 deg C. So water boiler no good, I would go stainless air to air, make your own.Yes it sounds a lot to me?
