Metallurgy Steam Atmospheric Pressure Fire Tube Boiler Manufacturers
atmospheric steam boiler - ncesdmath.org
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.

Characteristics of boiler feed water. It expands 1600 times as it evaporates to form steam at atmospheric pressure. The steam is capable of carrying large quantities of heat. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used

This is because the volume of hot water that would instantly turn to steam when the pressure dropped (eg because of a rupturing vessel) was vastly less than in even a small fire-tube boiler. Speaking of pressures, those achieved in the water tube boilers could be much higher than in a fire-tube design.
