Get a PID.
Yes.....pictures please. Our crystal balls are cloudy of late!

You don’t need air. JCI makes a simple controller w/ a 0-10 V or 4-20mA output. But on top of that you need a regular gas valve, thermocouple, corresponding transformers, butterfly valve and modulating actuator. It’s not going to have a PID loop w/ this setup as the “magic” is in the JCI controller and it’s just trying to maintain the set temp. It’s quite a bit of money if you want to put together a modulating gas burner setup.
Most industrial gas control systems are pneumatic. Some are electric. (pneumatic meets the fire and safety codes a lot easier than electrics!) Either way you are spending waaaaay too much money for all the bits-n-pieces. I have them all for free and I do not do it!
I know what it takes to do temp control right..........I design and sell them.

"Linotype melting pot"? Is the unit a part of a linotype type setting machine? I operated one during my first year of college circa. 1964, and my memory fails me. I just hung ingots on a hook and chain and fed the ingot into a pot built into the back of the machine...

I think the furnace in question was for recycling type slugs. The Linotype Machines had an electric pot and an electric motor and if I remember right plugged into a 120v outlet. The linotype ingots (pigs) had ears that hooked onto the chainfall that kept the casting pot full. I vaguely remember the letterpressmen melting the old slugs down and casting new ingots out back in the alley.

I have one of the old linotype machines ingot molds. The ingots weigh right around 22 pounds or so, depending on alloy...
Hope this helps.

There was no good way other than those ingots to feed the pot so I think most shops had molds and a "smelting furnace". I remember a pressman moaning. He ordered a pallet of linotype ingots rather than recycling slugs and the price of lino had gone to 27 cents a pound. "Can you believe it, 27 cents a pound?"

This is what I think also.
Glencoe use to have two newspapers. One is still alive, the other one ended a few years after the daughter (of the original owner) passed away at 90+ years old. Anyway, they had a complete linotype setup and I got a tour when the Paper had a open house with the new owner. The linotype machine had a electric pot on the machine (for pouring lines) and a large smelter in the back room to make heavy ingots from the used lines (there was three 55 gallon barrels full of lines). I don't recall if the large smelter was gas or electric?

When I was in college, I worked in the mail room of a moderate size newspaper, and the type setters were a short distance away from our shop. It was always hot in there, and noisy, but so was the mail room, where the papers came off the press. I once mentioned to one of the type setters that my Dad had a small boat and needed an anchor. When I left work that night, there were two ingots in the passenger's side floorboard of my car.
