BOILER TYPES FOR STEAM APPLICATIONS This article covers the basic difference between common boiler types for high pressure steam applications in the capacity range of 5,000,000 to 100,000,000 Btu/hr (5-100 MMBTU/hr or 120 - 2400 HP). This size

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.

Firetube boilers may be used in steam or hot water applications within the scope and service restrictions of ASME BPV Code Section I and ASME BPV Code Section IV. They may also be used to heat or vaporize liquids other than water, such as an organic or synthetic fluid. Firetube boilers can be constructed in different configurations.

The top water wall headers in water tube boiler have a mixture of steam and water and this is returned to the steam drum via tubes known as risers. Superheater Tubes: Once water gets converted to steam, its temperature needs to be raised further to pump in more energy in the steam and this is done by imparting thermal energy to the steam in the form of superheat.
