boiler has two fire tubes of diameter up to 40% of the diameter of the
shell. Flue gases pass through the fire tubes from side and bottom
space. The water level inside the drum is always above the side
channels of the flue gases, so more heat transfer to the water.
● Cornish
boiler consists of a single internal fire tube. The fire grate (furnace) is at
the front side of the tube and the coal goes through the fire hole into this
grate.
Hence, the
correct option is (D).
