Which of the following statements concerning fire-tube boilers is correct?
AI Explanation
You are correct, the statement "Combustion gases flow through the tubes" is the correct answer for fire-tube boilers.
In a fire-tube boiler, the combustion occurs in the furnace, and the hot combustion gases then flow through the tubes that are surrounded by water. This allows the heat from the gases to be efficiently transferred to the water, generating steam. The other options are incorrect because the flames do not impinge on the tubes, combustion does not occur in the tubes, and water does not flow through the tubes in a fire-tube boiler design.
