what is the cause of steam boiler

Scaling in boilers - Lenntech

Surging water levels in your boiler can be caused by numerous reasons but are usually a result of excess dirt or oil in the water. The condition is characterized by quickly changing water levels, which is generally due to inefficient steam release. Debris prevents steam from adequately escaping the water, causing it to rise and drop randomly.

Reasons why steam boilers flood, and where to look for

Apr 23, 2017 · Too-high pH in boiler water (water that is alkaline or "basic") causes frothing and surging. pH in a steam boiler should be between pH 7 and pH 9. A leak in a tankless coil used to make domestic hot water (not found on all steam boilers) will leak higher pressure (building water supply pressure) water into

SWELL AND SHRINK REACTION. Steam flow from the boiler is controlled by the downstream process (e.g. a turbine). A sudden increase or decrease in steam flow changes the pressure in the steam drum and boiler circuit. The change in pressure will cause a change in both the boiling point and density of the water and steam.
