, What are fire-tube boilers? - CORRECT ANSWER-Fire-tube boilers are steam
boilers designed with a cylindrical shell filled with water, where hot combustion
gases flow through tubes within the boiler.
List two advantages of fire-tube boilers. - CORRECT ANSWER-1. Compact size
and relatively simple design. 2. Quick heat transfer due to a large surface area for
heat exchange.
What industries commonly use fire-tube boilers? - CORRECT ANSWER-Power
plants, industrial processes, and heating systems in buildings.
What distinguishes water-tube boilers from fire-tube boilers? - CORRECT
ANSWER-Water-tube boilers have water-filled tubes that circulate hot
combustion gases, allowing for efficient heat transfer.
What are the two common types of furnaces in steam boilers? - CORRECT
ANSWER-1. Fire-tube furnaces. 2. Water-tube furnaces.
What is the function of a burner in a steam boiler? - CORRECT ANSWER-The
burner controls the flow of fuel and ensures efficient combustion to produce
heat.
