It consists of various components, such as fuel pumps, fuel lines, and fuel filters. The fuel supply system ensures a continuous and reliable supply of fuel to the burner, allowing for uninterrupted steam generation.

To ensure the safe and efficient operation of a fire tube boiler, it is equipped with various safety devices. These safety devices include pressure gauges, safety valves, and water level indicators. The pressure gauges monitor the pressure inside the boiler, while the safety valves release excess pressure to prevent any damage to the boiler. The water level indicators, on the other hand, monitor the water level inside the boiler and ensure that it is maintained at the desired level.

In conclusion, a fire tube boiler requires several key components for efficient steam generation. These components include the shell, fire tubes, combustion chamber, burner, fuel supply system, and safety devices. Each component plays a crucial role in the steam generation process, ensuring that the boiler operates safely and efficiently. By understanding the essential components of a fire tube boiler, one can appreciate the complexity and importance of this type of boiler in industrial settings.
