- Estimated study time: 30 minutes
Study resources
- Boiler Problems and Softening Methods - RGPV official notes (Article) — University-hosted PDF defining sludge vs scale (which salts cause which), priming, foaming and caustic embrittlement, plus prevention. Very close to exam answer format.
- Boiler Troubles / Boiler Feed Water - Poriyaan (Article) — Web page in clean point form: causes, disadvantages and prevention of each boiler trouble. Fast to revise on a phone.
- Boiler Troubles - Scale and Sludge Formation with Treatment (Er Sahil ka Gyan, Hindi) (Video) — Part of a full Hindi engineering-chemistry playlist. Covers scale, sludge and their removal in one sitting.
- Boiler Troubles - animated (sludge, scale, priming, foaming, caustic embrittlement) (Video) — Animated video that shows what is physically happening inside the boiler. The visuals make priming vs foaming much easier to keep apart.
- Boiler troubles: scale, sludge, priming and foaming - Engineering Chemistry (20AC14T) (Video) — College lecture recorded for I B.Tech I semester. Syllabus-aligned and covers all four terms in one video.
- Sludge and Scale Formation in Boilers - Dr. Anjali Saxena (Video) — Faculty lecture that sets out the four boiler problems that arise from hard feed water and then goes deep on sludge and scale.
