  Boiler Material - IB

  • OverviewThe first quality of a boiler material that comes to mind is ductility - you want a material that will withstand many,many heating and cooling cycles, with out fatiguing and cracking. Strength is almost secondary - the strength of a boiler is in its structure. Up to about 5 1/2 - 6" diameter and 100 PSI copper has many advantages,above that,low carbon steel is the material of choice. I worked as a …

20-04-2018· What are the materials of the pipes used in economizers and boiler tubes? Different materials are used in different zones of the Boiler depending on the temperature and pressure of the Steam inside the tubes and on the temperature of the flue gas. A general curve showing the property variation of metal with temperature is shown below.

Sandvik superheater tube and reheater tube materials cover all types of fuel, such as coal, gas, oil, black liquor and biomass. The Sandvik program also includes composite tubes consisting of two different alloys fully bonded together. Increased efficiency in coal-fired power boilers

In a water tube boiler fuel is fired into a water cooled furnace. Sheet metal and refractory enclosing the boiler called casing. At the end of the furnace, the flue gas turns into the convection section and travels towards the stack.

Designers use materials starting from carbon steel, to low alloy steel, to high alloy steel, and then to stainless steel to meet the requirements of the increase in metal temperature of the tubes as the steam picks up temperature in superheaters.

04-03-2020· A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. Advantages of Water Tube Boiler
