Since that would depend a lot on the design of the boiler it would be best to consult the Operating Manual or the manufacturer.

The blowdown interval time is the concentration ratio, multiplied by the blowdown event quantity, divided by the steam flowrate.

It also depends on the size of the blowdown valve relative to the volume and pressure of the water in the boiler; and possibly also on actual measurements of water condition.
