In the process of industrial boiler operation, the change of steam pressure essentially reflects the change of the balance between boiler evaporation and external load.Therefore, Zhengzhou Fang Kuai Boiler Plant to remind you: the operation of industrial boilers should pay attention to the change of steam pressure.

 

There are two main reasons for the change of steam pressure:

(1) external disturbance.It is the change of steam pressure caused by the change of external load.When the boiler evaporation is lower than the external load, that is, when the external load suddenly increases, the steam pressure is reduced, when the evaporation is just to meet the external load, the steam pressure remains normal and stable.

(2) Internal disturbance.It is the change of steam pressure caused by the change of working conditions in the boiler.Such as the change of combustion conditions, the change of fuel properties, the start and stop of the nozzle, the start and stop of the pulverizing system, the ash accumulation and coking in the furnace, the change of the ratio of wind and coal, and the influence of the scale in the heating surface pipe heat exchange or leakage, pipe explosion, etc. will make the steam pressure change.
