At the same time, the cold start up parameters for this boiler were measured and compared with our simulation results. Natural (or thermal) circulation boilers Referring to figure-1 (a), in the downcomer (pipe through which flow is directed downwards), no steam is present and the tube section A-B is not heated. by a steam turbine. To regulate the flow through various tubes, orifice plates are used. The level control on each boiler operates its respective pump. This control would indicate to me that one of the boilers is standby most of the time. Shortly thereafter the controlled circulation concept reached full commercial development and was widely used in public utility central stations throughout the world. This differs from a natural circulation boiler which relies. See other definitions of CFC. There is a Wilo circulating pump on this loop mounted on the return side just before the boiler.

Concept: 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 generating tubes are installed at a slight inclination which allows the lighter hot water and steam to rise and the cooler and heavier water to descend. Circulator pumps use water to move heat all over a building or even a property. Circulator pumps literally move hot water. Controlled circulation boilers. These are natural circulation based on the conventional "thermal circulation head," and controlled circulation based on the use of a pump to distribute and circulate the water through the heat-absorption areas.
