Julio, Do you mean how frequent you spall? We go by the highest skin temperature, usually near the outlet of the pass. We monitor flow (we use BFW), inlet pressure, and pass skin temperature near outlet and the outlet temperture. We do one pass at the time. On line spalling is done every 7-8 months (depends on what skin temperature target you use).
