Name the major components of a typical fire-tube boiler.

A typical fire-tube boiler operates on the principle of hot gases flowing through tubes that are surrounded by water. The major components integral to this system include the combustion chamber, flue gas passages, and fire tubes.

The combustion chamber is where fuel is burned to generate heat. This heat then travels through the flue gas passages, which are designed to direct and manage the flow of exhaust gases produced during combustion. The fire tubes are specifically designed to carry these hot gases while submerged in water, allowing heat transfer to occur effectively, thereby raising the temperature of the water and producing steam.

Understanding these components is crucial for recognizing how fire-tube boilers function, as each part plays a vital role in generating steam and managing heat transfer. The way in which these components interact directly impacts the efficiency and effectiveness of the boiler system.
