Forced circulation boiler - Wikipedia

That is to say that as the water is heated and starts turning to steam, the density decreases sending the hottest water and steam to the top of the furnace tubes. In contrast to the natural circulation boiler, the forced circulation boiler uses a water circulation pump to force that flow instead of waiting for the differential to form.
