natural circulation high pressure boiler

Corrosionpedia - What is Natural Circulation? - …

Therefore, boilers in which the tubes slope quite steeply from steam drum to water drum are said to have natural circulation of the accelerated type. Natural circulation evaporators are very simple and are normally used where the effluent has a high viscosity, higher levels of hardening agents, un-dissolved solids, for products which are

Natural Circulation - an overview ScienceDirect Topics

Vertical natural-circulation designs did not really come into favour until the arrival of the larger F-class gas turbines wich were capable of supporting a three-pressure steam cycle. A typical steam cycle for the early F-class would have 100 bar for the high pressure, 30 bar for the intermediate pressure and 5 bar for the low pressure.
