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 boilers yield a bigger ...

BASIC STEAM CYCLE/BOILERS | Marine Notes

Steam is the working substance used for the propulsion of many surface ships including nuclear and conventionally powered steam ships. Central to understanding the operation of steam propulsion is the basic steam cycle a process in which we generate steam in a boiler expand the steam through a turbine to extract work condense the steam into water and finally feed the water back to the boiler.
