Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

The National Board of Boiler and Pressure Vessel Inspectors

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.

How to size a Circulator Pump. Taco pump curves.

All circulator pumps are typically sized based on the heat load and head loss (pressure drop) for a given zone. Knowing the heat load (in BTU's) for a given zone, allows to calculate the required circulator pump's flow rate in gallons per minute (GPM). For hot water hydronic or radiant heating applications, the following equation can be used:
