What are the construction materials used in a water tube boiler?
Boiler Tubes
- For moderate pressure services tubes are made from strips of steel which are formed into tube shape and edges are welded in an electrical resistance welding machine.
- Tubes for high pressure service are usually made by piercing a solid round billet of heated steel to form a rough tube.
How is boiler made?
Modern boilers are made of alloy steel to withstand high pressures and extremely high temperatures. In the fire-tube type, the water surrounds the steel tubes through which hot gases from the furnace flow. The steam generated collects above the water level in a cylindrically shaped drum.
What are the construction materials used in a water-tube boiler?
Which of the following material is not used in boiler furnace walls?
4. Which of the following material is not used in the boiler furnace walls? Explanation: Fire clay, Silica and Kaolin have property of resisting change in shape, weight or physical property at higher temperature. Concrete have no such properties at higher temperature so it is not suitable for that.
What is boiler steel?
Boiler quality steel is a group of steels is that is used in a variety of industries for the fabrication of boilers and pressure vessels. When steel is described as boiler quality steel it is capable of being used in a variety of vessels to withstand high pressures.
