Does a long-term steam output from the boiler that exceeds its designed output have an impact on its long-term operation? If there is an impact, which components are affected?
When the boiler is overloaded, the steam-water separator carries residual water to the superheater, and over time the superheater will develop scale.
How much more do you have? Generally, if it’s 10% above the normal value, it’s not a big problem!
Generally, it should not exceed the specified design elasticity; if this limit is exceeded for a long time, fatigue can occur leading to tube rupture accidents
Excessive overload can affect the two-phase balance in the steam drum, resulting in a reduced effectiveness of the chemicals used for treatment. Operating in this manner over a long period has a significant impact on the quality of the steam; it not only facilitates scaling in the boiler tubes but also leads to scaling and corrosion in the steam transmission pipelines and equipment that use steam. Scaling occurs especially in places such as the control valves, metering orifices, branch reducers, and filters in steam systems.
