In energy type equipments such as steam pipelines, boilers, super heaters, boiler tubes are specially manufactured to withstand high pressure and temperature.
Carbon steel and alloy steel are common materials for boiler tubes, which are seamless tubes. They are commonly used in steam boilers, power plants, fossil fuel plants, industrial processing plants, electric power plants, and many other applications.
– Fire Tube Boiler:As implied by the name, the fire tube boiler consists of a number of tubes that pass hot gasses through them. These hot gas tubes are immersed in a closed vessel that is filled with water.
2. Lancashire BoilerThere is a heating system in Lancashire boiler which works on the principle of a heat exchanger. The heat is transferred from exhaust gases to water by convection.
A drum is filled with feedwater. The drum is placed over the heat source. Cooler water goes to inclined tubes, which eventually heat up in the hot tubes.
There is a cross-section between the drum and the heat source in this type of arrangement. This type of arrangement results in a more uniform temperature.
