vi. Maintain the lowest water level in the boiler drum or separator; vii. Kill the steam generator fire and rapidly open the temporary blow-out valve; viii. In order to restrict drop in saturation temperature during blowing to 40 K, close the temporary blow-out valve once the steam pressure drops down to 1.9–3.1 MPa (main steam and HP bypass lines) or to 2.5–3.7 MPa (cold reheat and hot
