Internally rifled boiler tubes are used to evaporate water into steam inside boilers of thermal power plants.Because of their internally rifled shape, they are more efficient. The boiling crisis takes place later, thus allowing for greater heat transfer between the pipe and the fluid inside the pipe. Costs of this type of tube are generally higher than plain tubes.
suijitupian36.jpg" />Fire-tube boiler: This is a boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.; Since fire is inside the tubes and hence it is named as fire tube boiler.The heat from the hot gases is conducted through the walls of the tube to the water.
