Working of Locomotive Boiler | Parts of Locomotive Boiler | Advantages of Locomotive Boiler | Disadvantages of Locomotive Boiler

As the fuel starts burning in the furnace, hot gases are released from the burning fuel, and these hot gases enter the fire tube. Now the gases will flow through flue pipes and heat these flue pipes. A fire brick arch exists that provides a passage and direction for the flue gases to reach the flue gases and prevents solid fuel particles from entering the fire tubes.
