EC: Lesson 11. Scale and sludge formation in boilers

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

2. Sludge-Along with the dissolved solids, there are some suspended solids in the boiler feed water. These suspended solids get precipitated as sludge. Sludge is normally soft in nature compared to scales, but many times sludge gets hardened because of heating inside the boiler. This heating many times makes the removal of sludge quite a
