Q5. Types of steam produce by boiler
Ans. 
Boilers produce two types of steam: saturated and superheated.
• Saturated steam is produced when water is heated to its boiling point and vaporizes with no further increase in temperature.

• Superheated steam is produced when saturated steam is heated above its boiling point, resulting in a higher temperature and energy content.

• Saturated steam is commonly used for heating and power generation, while superheated steam is use...read more
