The forced circulation boiler begins the same as a natural circulation boiler, at the feed water pump. Water is introduced into the steam drum and is circulated around the boiler, leaving only as steam. What makes the forced circulation boiler different is its use of a secondary pump that circulates water through the boiler.
A LaMont boiler is a type of forced circulation water-tube boiler [1] in which the boiler water is circulated through an external pump through long closely spaced tubes of small diameter. The mechanical pump is employed in order to have an adequate and positive circulation in steam and hot water boilers.
La Mont boiler: a forced-water-circulation boiler. [33] They are often used as marine heat-recovery boilers. [33] It was also used, unsuccessfully, for an experimental steam locomotive in East Germany in the 1950s. [34] Lancashire boiler: a development of the Cornish boiler, with two flues.
Diagram showing the arrangement of the boilers (brown), turbines (pink), and turbo generators (dark gray) The Richelieu-class ships were powered by four Parsons geared steam turbines and six oil-fired Sural forced-circulation boilers manufactured by Indret for Richelieu and by Penhoët and AC de la Loire for Jean Bart.
A forced circulation reboiler (Image 4) uses a pump to circulate the column bottoms liquid through the reboilers. This is useful if the reboiler must be located far from the column, or if the bottoms product is extremely viscous.

A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler. [1]
USAID delivers billions of dollars in humanitarian aid, funding that advocates say provides a critical lifeline to more than 100 countries at only a small fraction of the overall federal budget.
