Energy Recovery
Stenter exhaust is hot, clean enough and never stops. Of all the heat a finishing plant wastes, this is the heat worth chasing first.

Sensible heat only. Stenter exhaust also carries moisture and condensable oils, and recovering the latent heat means dropping below dew point — which is where fouling and acid condensate start. Size the exchanger for the fouled condition, not the clean one, and include cleaning downtime in the payback.
