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 pressure difference between the heated and unheated sections and consequently produce bigger flow rates.
