What materials are currently used in boiler tubes?

Boiler tubes are seamless tubes and are made of either carbon steel or alloy steel. They are widely used in steam boilers, for power generation, in fossil fuel plants, industrial processing plants, electric power plants, etc. Boiler tubes can either be medium-pressure boiler pipe or high-pressure boiler pipe.

What are the types of water tube boilers?

Types of Water Tube Boilers

• Simple Vertical Boiler.
• Stirling Boiler.
• Babcock and Wilcox Boilers.

What provides boiler water circulation to the waterwall tubes?

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.

How does a water tube boiler work?

In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam.

Which metal is used for making boiler?

The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron.

What causes failure of boiler tube?

Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow.

Where are water tube boiler used?

Water tube boilers can generate saturated or superheated steam, which is useful for applications such as steam turbine power generation. In addition, these boilers are commonly used in process industries, including chemicals , refining, and pulp and paper manufacturing.

What are the difference between fire tube boiler and water tube boiler?

The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.

What is the difference between fire tube boiler and water tube boiler?

What is difference between pressure cooker and boiler?

Pressure cooking requires much less water than conventional boiling, so food can be ready sooner. Less energy is required than that of boiling, steaming, or oven cooking. Since less water or liquid has to be heated, the food reaches its cooking temperature faster.
