Water Tube Boilers - beta.spiraxsarco.com
Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off. However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs.
