3 Types of Circulation In Boiler - Water Treatment Basics

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 winters day. Warm air rises on the wall where the room is heated; subsequently, cooled, more dense air falls downwards on the opposite wall.

12/06/2019 · Under the subcritical pressure, the natural circulation boiler with the flue gas parameter of 16.6~18.2 MPa and the working pressure of the drum reaches 18.6~20.6 MPa, and the natural circulation still has sufficient water circulation driving force to achieve safe and reliable operation. 2. Has a fixed evaporation section end point.

What is Natural Circulation? - Definition from Corrosionpedia

13/01/2015 · 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 is heated, and thus, becomes less dense.
