70% to passWhich of the following statements concerning fire-tube boilers is correct?
ACombustion gases flow through the tubes.
BFlames impinge on the tubes.
CCombustion occurs in the tubes.
DWater flows through the tubes.
AI Explanation
The correct statement concerning fire-tube boilers is A) Combustion gases flow through the tubes. In a fire-tube boiler, the hot combustion gases from the furnace flow through the tubes that are surrounded by water. This allows the heat from the gases to be transferred to the water, generating steam. The other options are incorrect because in a fire-tube boiler, the flames do not impinge on the tubes (B), the combustion does not occur inside the tubes (C), and the water does not flow through the tubes (D).
