1.Continue to ventilate five minutes. Exclude remaining combustible material from the combustion chamber and flue, and then close the throttle and stop blower and induced draft fan operating, which can prevent the cooling causing the vapor pressure to drop too fast.
2.Keep the primary and secondary bypass after the flameout, or open primary bypass and reheater for exhausting steam, turn off after 10 ten minutes to maintain the superheater and reheater from overheating.
3. When the boiler is turned off, please strictly control the speed of the boiler buck, take the natural pressure relief mode. It is strictly forbidden to exhaust steam for forced decompression, so as not to damage the equipment.
4. When the boiler has pressure and auxiliaries have power, the boiler unit is not allowed to monitor.
5.In order to prevent heating surface of the boiler from corrosion, doing well in maintenances when the boiler is turned off according to the requirements.
