What is the difference between a superheated steam boiler and a general steam boiler?
A superheated steam boiler and a general steam boiler differ in the temperature and pressure of the steam they produce.
A general steam boiler produces steam by boiling water and generating steam at the saturation temperature corresponding to the pressure of the boiler. The steam produced is typically saturated steam, which means it contains moisture in addition to the steam. This moisture can cause damage to equipment and reduce the efficiency of steam-based processes.
In contrast, a superheated steam boiler produces steam at a higher temperature and pressure than a general steam boiler. This is achieved by passing the steam through a superheater, which raises the temperature of the steam above its saturation temperature. The resulting steam is dry and contains no moisture, which makes it more efficient for use in industrial processes.
Superheated steam boilers are commonly used in power plants, chemical plants, and other industrial applications where dry steam is required. They are also used in some locomotives to produce high-pressure steam for the turbine engine. However, they are more complex and expensive to operate and maintain than general steam boilers.
As mentioned earlier, the primary difference between a superheated steam boiler and a general steam boiler is the temperature and pressure of the steam they produce. In a superheated steam boiler, the steam is heated to a temperature above the saturation temperature corresponding to the pressure of the boiler. The steam is then passed through a series of tubes or other heat exchangers, where it is further heated to the desired temperature.
The advantages of superheated steam over saturated steam include:
Increased efficiency: Superheated steam contains no moisture, which means it has a higher enthalpy and can transfer more heat energy than saturated steam. This makes it more efficient for use in industrial processes.
Reduced condensation: Because superheated steam is dry, it does not condense as easily as saturated steam. This means that it can be used in applications where condensation would be a problem, such as in high-temperature heat exchangers.
Improved control: Superheated steam can be more precisely controlled than saturated steam, which makes it more suitable for use in certain industrial processes.

On March 20, 2025, the Guizhou Jinyuan Zhijin “Replacing Small Units with Large Ones” Relocation Project (2×660 MW), under State Power Investment Corporation, successfully achieved the first ignition of its boiler. This project replaced traditional oil-fired ignition fuel with liquefied natural gas (LNG), setting a new precedent for employing clean energy in 660 MW ultra-supercritical “W” flame boilers. As a key equipment supplier for this project, ZOZEN Boiler prov...15 Jul 2025
