the natural circulation principle of the steam boiler Agent

Boiler circulation systems: natural circulation and forced …

In natural or thermal circulation type boilers, the rate of circulation depends strongly on the density difference between the unheated water and the heated steam-water mixture. The overall circulation rate (flow) in natural circulation systems mostly depends on the following factors: - Height of the boiler - Taller boiler…

What are the circulations used in boiler--ZBG Boiler

13/1/2015 · 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.
