Four parts in gas steam boiler should be focused

After finishing the work, following the steam boiler is powered down, oxygen may never confined places in to the steam boiler steam water, and built-into the boiler, in the event the pressure and temperature in decline, next the oxygen will likely be condensed into water vapour, after which helps make the metal surface of boiler damp, thus causing the water film. If, inside the steam boiler disabled, some parts still soaked in said in words, then water vapour through evaporation, the steam water creates a large numbers of moisture, so the boiler corrosion phenomena. So for natural gas fired boiler in the boiler market,which parts of the easy corrosion?
1, Economizer Section of boiler, in operation, the entrance places are incredibly simple corrosion, more don't say economizer following your shutdown.
2, if the water wall running, the deoxidization effect it is poor, so its drum and down comer is extremely simple to corrosion. It is easy to corrosion functioning, in the side wall with the drum boiler stop edge especially serious.
3, inside vertical superheater steam boiler elbow places, because long-term around the water, water removal just isn't clean, so also generated its rapid corrosion.
4, the reheater and superheater are vertical, elbow exposed to corrosion in water immersion.
Over the above description, so long as the interest in the four aspects of taking care , then industrial steam boiler life may be extended.
