Q3. Types of steam produce by boiler
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 used in industrial processes such as turbines and engines.

Q4. What is boiler why u steam
A boiler is a closed vessel in which water or other fluid is heated. Steam is produced as a result of the heating process.
Boilers are used to generate steam for various purposes such as heating, power generation, and industrial processes.
The heat source for a boiler can be natural gas, oil, coal, or electricity.
Steam produced by a boiler can be used in heating systems, power plants, and manufacturing processes.
Boilers are essential in industries like food processing, chemical...read more
Q5. Welding electrodes used in fabrication
Welding electrodes are used in fabrication to join two metal pieces together.
Welding electrodes come in different types and sizes depending on the metal being welded and the welding technique used.
Some common types of welding electrodes include stick electrodes, MIG electrodes, and TIG electrodes.
The choice of welding electrode also depends on the thickness of the metal being welded and the welding position.
Proper storage and handling of welding electrodes is important to pre...read more
Q6. Boiler types and steam
Boilers are classified into fire-tube and water-tube types. Steam is generated by heating water in the boiler.
Fire-tube boilers have hot gases from combustion passing through tubes which are surrounded by water.
Water-tube boilers have water flowing through tubes which are heated by hot gases from combustion.
Steam is generated when water is heated in the boiler and the resulting steam is used for various applications such as power generation, heating, and industrial processes.

Q7. Y using prv in steam line
PRV is used in steam lines to protect the system from overpressure by releasing excess steam.
PRV helps prevent damage to equipment and ensures safety by releasing excess steam when pressure exceeds set limits.
It helps maintain a constant pressure in the steam line, preventing fluctuations that can affect the system.
PRV is essential in steam systems to prevent accidents and ensure efficient operation.
Examples: PRV installed in a boiler system to prevent overpressure and in a s...read more
Q8. Bed height of boiler
Bed height of a boiler refers to the height of the bed of solid fuel in the combustion chamber.
Bed height is an important factor in determining the efficiency of a boiler.
It affects the combustion process and the amount of heat transfer to the water.
The ideal bed height varies depending on the type of fuel and the design of the boiler.
For example, a bed height of 6-8 inches is recommended for coal-fired boilers.
Regular monitoring and adjustment of bed height is necessary for ...read more
