Chamber oven above 1000˚C
“Mixing atmosphere with a strong impulse.”
To achieve evenness, chamber ovens have built-in burners that mix the atmosphere with strong impulses; in a specific part of the curve they reach 70 % efficiency or fail to work.
Sometimes such ovens require a specific atmosphere (oxidation, reduction or a combination of the two – oxidation at the beginning and reduction towards the end).
The temperatures rise and fall along the curve.
The unique feature of such ovens is insulation, as each cycle needs to be heated and cooled-down again, constituting significant energy loss.
