For a boiler producing saturated steam, half-load operation demands no special consideration. However, for a HRSG designed to produce superheated steam, the gas flow and temperature at reduced load might dictate a change in superheater arrangement, a different tube material, and revised thinking with respect to the superheater. Supplementary firing

In a fire tube boiler, hot gases are inside the tube and water is at outside the tube, while water tube boiler has water inside the tube and gases on the outside. Fire tube boilers produce lower rate of steam compared to water tube boilers. The focus for this will be on HRSG with water tube boilers.

The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.
