Boiler circulation systems: natural circulation and forced ...

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. Heat input generates a steam-water mixture in section B-C usually referred to as riser (pipe through which flow is directed upwards).

Boiler circulation systems: natural circulation and forced ...

Natural versus forced circulation typical schematic. 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 rate (flow) in systems mostly depends on the following factors: - Height of the - Taller yield a bigger pressure difference between

A drumless natural circulation boiler system has a furnace enclosure with wall tubes and upper and lower headers connected to respective upper and lower ends of the wall tubes. At least one tangential steam/water separator is connected to a plurality of riser tubes that are also connected to the upper headers. The riser tubes return a steam/water mixture to the separator.
