What is Natural Circulation? - Definition from Corrosionpedia

In natural circulation boilers, the circulation of water depends on the difference between the density of an ascending mixture of hot water and steam, and a descending body of relatively cool and steam-free water. The difference in density occurs because the water expands as it

Natural Circulation - an overview ScienceDirect Topics

4.1.2 Natural Circulation Boiler. Natural circulation is based on density differences. The same principle can be seen in, e.g., room on a cold winter's day. Warm air rises on the wall where the room is heated; subsequently, cooled, more dense air falls downwards on the opposite wall.
