TEKNE Engineering

The time-domain analysis reveals a periodic, low-frequency stimulus (0.5 Hz-1 Hz), which can be correlateci with operating conditions. In the case of operations 3 and 6, a significant attenuation of vibrations outside the furnace is detected both instrumentally and visually (absence of significant peaks).
