Smoke tube boilers. - In smoke tube boilers, hot flue gases flowing through the tubes are surrounded by water on the outer surface. - These boilers have low evaporation rates because they have large water to steam ratio. Due to high ratio of water and steam, the temperature stresses which cause failure of feed water arrangement are minimum.
