What equipment adds heat to steam within a boiler?

The superheater is a crucial component within a boiler system that increases the temperature of steam after it has been generated but before it is sent to the steam turbine or process application. By adding heat to the steam, typically using hot flue gases from the combustion process, the superheater enhances the thermal efficiency of the boiler system.

This increase in temperature allows the steam to carry more energy, resulting in improved performance and efficiency when it is used to drive turbines or perform work in various industrial processes. Superheated steam can also help in minimizing the chances of condensation within the steam pipes, which can lead to water hammer and reduce the overall efficiency of the steam system.

The other components mentioned do serve important functions in the boiler system, but they do not add heat to the steam itself. An economizer is primarily used to preheat the feedwater using flue gases, which enhances overall efficiency but does not heat steam. The boiler feed pump is responsible for supplying water to the boiler but does not directly heat the steam. An evaporator is used in different applications and focuses on turning liquid into vapor but is not part of the conventional steam generation process in a high-pressure boiler. Thus, the superheater plays a distinctive role in enhancing the quality and energy content
