b) Fire tube uses water, while water tube utilizes steam.
c) Fire tube has tubes containing hot gases; water tube has tubes containing water.
d) Fire tube boilers are used for industrial purposes; water tube boilers for residential heating.

Answer 1

The operating principle of a fire tube boiler involves the transfer of heat from the hot gases to water, while in a water tube boiler, the heat is transferred from the hot gases to the water inside the tubes. option c is correct

Step-by-step explanation:

In a fire tube boiler, the hot gases produced by the combustion of fuel inside the furnace pass through tubes surrounded by water. The heat from the hot gases is transferred to the water, which is heated and converted into steam.

On the other hand, in a water tube boiler, the water is inside the tubes while the hot gases flow around them. The heat from the hot gases is transferred to the water inside the tubes, which is also converted into steam. . option c is correct
